An experimental study of sunflower seed husk and zeolite as adsorbents of Ni(II) ion from industrial wastewater
Due to the structural similarities, sunflower seed husk (SSH), an agricultural, low-cost, and eco-friendly waste, is employed interchangeably with zeolite to extract Ni (II) ions from model and real industrial wastewater in this work. Batch experiment adsorption was carried out to investigate the possibility of Ni (II) ion removal by adsorbents. Zeolite powder and SSH were used in three different sizes and without any modifications to optimize the effect of adsorbent size. The maximum adsorption rate of 76% for the bulk size of SSH was obtained at pH 6.5, 20 g/L of adsoadsorbent, an initial concentration of ions of 20 mg/L, and 2 h of contact time. Thermodynamic results showed that the process is spontaneous, feasible, and exothermic within the set temperature range (10°C-80 °C). It can be concluded from the results that SSH can be used as a feasible, eco-friendly, and biodegradable organic material for Ni ion adsorption.

Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
