Sorption kinetics for the removal of copper and zinc from effluents using bone char

摘要: Abstract The removal of copper and zinc ions from aqueous effluents by bone char has been studied in single component sorption systems. capacity for is 0.75 0.53 mmol per g char, respectively. values indicate that a suitable sorbent the two metal ions. equilibrium isotherms are best described Langmuir–Freundlich (L–F) type isotherm equation. kinetics have analyzed kinetic models, namely, Lagergren pseudo first-order model Elovich model. Kinetic analysis models carried out system variables — initial ion concentration mass char. rate constants determined correlation coefficients calculated order to assess which provides fit predicted data with experimental results. equation data.
