The suspension was agitated in a shaker and samples were taken at known time intervals for the purpose of studying the kinetics of the sorption process. Otherwise, the samples were allowed to reach equilibrium (24 h) and then filtered. The residual Cu2+ or Zn2+ ion content in the filtrate was analyzed using a Varian Spectro AA10 atomic absorption spectrophotometer. Two replicates per sample were used with the average results being presented in this work. A blank experiment was conducted in the absence of sorbent and no metal sorption by the bottle or by the filter paper employed was detected.
