This study investigates the kinetics and equilibrium of phenolic derivative detoxification from aqueous solutions using activated carbon derived from coconut husk (CHAC). Phenolic compounds, prevalent in industrial wastewater, are highly toxic to humans and aquatic life. The removal efficiency of 4-Nitrophenol (PNP) and 4-Chlorophenol (PCP) was examined using batch adsorption experiments under varying conditions including adsorbent dose, contact time, initial concentration, and temperature. Coconut husk was chemically activated and characterized for its adsorption properties. The optimal adsorbent dose for PNP removal was determined to be 0.2 g, achieving a maximum adsorption capacity of 64.65 mg/g after 120 minutes. Adsorption data were fitted to pseudo-first-order and pseudo-second-order kinetic models to understand the adsorption mechanism. The results indicated that the adsorption of PNP onto CHAC followed the pseudo-second-order kinetic model, suggesting chemisorption as the dominant process. The findings demonstrate that activated carbon from coconut husk can be an effective and sustainable adsorbent for removing phenolic derivatives from wastewater, offering a potential solution for environmental detoxification. Further studies on isotherm models and thermodynamics are recommended to optimize the adsorption process for large-scale applications.

Euphorbia hirta L. is an herbaceous plant used in traditional medicine to treat several diseases. In the present work, different fractions of Euphorbia hirta L. hydroalcoholic extract were investigated for their anti-diabetic properties on α-glucosidase’s inhibition activities. Chemical screening realized following Folin-Ciocalteu and AlCl3 methods showed that ethyl acetate (AcOET) and butanol (BuOH) extracts contain 432.687 ± 1.832 µg and 332.433 ± 1.255 µg GAE/mg of extract for phenolic compounds. The same extracts contained high levels of total flavonoids estimated at 417.850 ± 15.941 µg and 227.640 ± 2.657 μg QE/mg of extract respectively. The anti-diabetic activities revealed that AcOET and BuOH have a very significant inhibitory potential on the enzymatic activity of α-glucosidase with an IC50 values of 1.295 ± 0.035 μg/mL and 2.188 ± 0.204 μg/mL respectively compared to acarbose (IC50 = 214.825 ± 3.816 μg/mL).

Heavy metals such as copper are not only a problem for air pollution: they are bio persistent, disrupt ecosystems, damage soils, surface waters, forests, and crops, and accumulate in the food chain. The aim was to propose effective methods for quantifying and decontaminating wastewater containing copper. In this study, the treatment of copper(II)-containing wastewater was carried out using clay, and the concentration of Cu2+ was monitored using the differential pulse anodic stripping voltammetry method. Physical characterization revealed the porous nature of our clay. Furthermore, the kinetic study of Cu2+ adsorption on clay is adapted to the pseudo-order 2 kinetic model, and the appropriate isotherm is that of Langmuir with an equilibrium time of 20 min. Cu2+ adsorption is maximal at pH = 6. The maximum monolayer adsorption capacity was found to be 66.54 mg/g.

The effect of surface modification on the mechanical properties and water absorption of Raphia farinifera (raphia fibre) were examined. The fibre was treated with 2% benzoyl peroxide in acetone, 10% potassium hydroxide, 25% hydrogen peroxide and 1% potassium permanganate in one hour. The mechanical properties; tensile strength, load at break, modulus and water absorption properties were investigated and results compared with control (untreated fibre). The results of the mechanical properties showed that the tensile strength of the fibre (Raphia farinifera) improved from 50.1142MPa for the untreated fibre to 132.3482MPa for potassium hydroxide treatment and 146.0181MPa for hydrogen peroxide treatment. Benzoyl peroxide treatment showed superior load at break value (25.5617N) over the untreated fibre (14.7847N). The results of water absorption showed that the treatment of the fibre reduced the hydrophilic nature of this fibre. However, benzoyl peroxide treatment showed highest reduction in water absorption capacity of the fibre followed by potassium hydroxide treatment.

Iodine deficiency (ID) is the result of insufficient dietary iodine intake in humans, the deficiency not only leads to goiter formation but also to severe retardation of growth, development and maturation of nearly all the tissues of the body, especially those that are fast developing. The aim of this research is to evaluate levels of iodine intake by ten Nigerian vegetables using copper complex. Dry alkaline ash method was used in the determination. The results obtained showed that all the ten vegetables used absorbed high concentrations of iodine when inoculated with 0.09 M and 0.14 M [Cu(I)4]2- . Iodine phytotoxicity was observed in all the plants when inoculated with 0.2-0.8 M of the copper complex as all the plants died. Increase in the concentration of copper complex from 0.09-0.14 M increased the absorption of iodine by Amaranthus hybridus, Corchorous olitoruis, Gongronema lotifolium and Solanum melongena. The reverse was observed with Murraya koenigii, Ocimum gratissimum, Talinium triangulare, Abelmoschus esculentus, Cucurbita pepo and Telfairia occidentalis. Ocimum gratissimum absorbed the iodine at 0.09M with value of 164.79 mg/kg, the vegetable also absorbed least at 0.14 M with a dose of 61.80 mg/kg. The intake of the iodine by the plants showed that the method can be used in the fortifying these Nigerian vegetables with iodine, thereby reducing the incidence of Iodine deficiency disorder in humans.
碘缺乏症（ID）是人类从膳食中摄入碘不足的结果，碘缺乏症不仅会导致甲状腺肿的形成，还会严重阻碍几乎所有人体组织的生长、发育和成熟，尤其是那些发育较快的组织。本研究的目的是利用铜络合物评估尼日利亚十种蔬菜的碘摄入水平。测定中使用了干碱灰分法。结果表明，当接种 0.09 M 和 0.14 M [Cu(I)4]2- 时，所有十种蔬菜都吸收了高浓度的碘。当接种 0.2-0.8 M 的络合铜时，所有植物都出现了碘植物毒性，因为所有植物都死亡了。络合铜浓度从 0.09 到 0.14 兆帕时，杂交马齿苋（Amaranthus hybridus）、鹅掌楸（Corchorous olitoruis）、荷包牡丹（Gongronema lotifolium）和茄科植物（Solanum melongena）对碘的吸收增加。而鹅掌楸、金丝桃、三棱草、鹅掌楸、葫芦科植物和西洋接骨木对碘的吸收则相反。 莴苣在 0.09M 浓度下的碘吸收率为 164.79 毫克/千克，在 0.14M 浓度下的碘吸收率最低，为 61.80 毫克/千克。植物对碘的吸收情况表明，该方法可用于尼日利亚蔬菜的碘强化，从而降低人类碘缺乏病的发病率。

The aim of this research is to evaluate levels of iodine intake by ten Nigerian vegetables using copper complex. Dry alkaline ash method was used in the determination. The results obtained showed that all the ten vegetables used absorbed high concentrations of iodine when inoculated with 0.09 M and 0.14 M [Cu(I)4]2- . Iodine phytotoxicity was observed in all the plants when inoculated with 0.2-0.8 M of the copper complex as all the plants died. Increase in the concentration of copper complex from 0.09-0.14 M increased the absorption of iodine by Amaranthus hybridus, Corchorous olitoruis, Gongronema lotifolium and Solanum melongena.

Vegetables, fruits and grains are sources of food rich in vitamins, minerals, and fibers and also have beneficial ant oxidative effects Pesticides and trace metals typically contaminate these food products. Pesticides and trace metals are not biodegradable and have the potential for accumulation in different body organs, leading to unwanted side effects This study investigated the concentration of pesticide residues and some selected Trace metals in Vegetables, fruits and grains from Odolua market Ile-Oluji Ondo State. Samples were collected randomly from the market, representative portion of the samples was chopped into small pieces and blended using a blender..Quantitative determination of the pesticide for Herbicides, organochlorine and organophosphate was carried out using Gas Chromatography-Mass Spectrometer after liquid-liquid extraction. Trace Metal was determined using Inductively coupled plasma - optical emission spectrometry (ICP-OES). The results reveal the presence of pesticide residues in all the samples. The mean concentration of pesticides in the samples was below the maximum residue limits (MRs) value for World health organization (WHO) while some were higher. The results also shows that all the trace metals analyzed are present in the samples except for Cadmium which is below the detection limit while Lead and Cobalt are only detected in one sample each. Some concentrations of the trace metals were below the permissible limit for WHO while others were higher than the permissible limit.
