Abstract
The goal of this investigation effort was to organize activated carbon from olive stone through by 0.01 M D2EHPA. The adsorption ability of carbon with cadmium and zinc existed also studied. Focuses of metals were examined through using flame atomic absorption spectrophotometry. The factors that disturb the adsorption, such as contact time, acid concentration, solid liquid ratio, RPM, and temperature, have been considered and enhanced conditions were determined. The results showed that the maximum adsorption capacities of carbon were found to Cd2+ and Zn2+with 28.0 and 22.17 mg/g, respectively. The Langmuir adsorption model might be used to clarify the adsorption isotherm with the pseudo-second order and The Cd2+ and Zn2+sorption process onto the olive stone (OS) occurred spontaneously (–ΔG), in an exothermic nature (–ΔH), and with increased non randomness (–ΔS).
期刊介绍:
Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
