摘要
This article presents the results of research on the comparison of Pb2+ sorption from aqueous solutions on walnut shells with that on plum stones. For walnut shells the depletion of Pb2+ in the solution was 62.9-83.7% and for the plum stones, 47.2-81.3%. The effect of various factors, such as the concentration of natural sorbent, pH, and temperature was studied. The process of Pb2+ ion sorption on walnut shells and on plum stones was described by the Langmuir and Freundlich models. The maximum sorption capacity of walnut shells was for 23.1 mg/g, whereas for plum stones it was 21.2 mg/g.
