The treatment of chromium wastewaters using the sorptive potential of leaf mould

Previous work has shown that a range of relatively low-cost organic materials can be used to absorb chromium ions from aqueous solution. The results of batch adsorption trials indicate that leaf mould also has the potential for use in this way. The optimum pH for the process was found to be 2·0, wit...

Zusammenfassung:Previous work has shown that a range of relatively low-cost organic materials can be used to absorb chromium ions from aqueous solution. The results of batch adsorption trials indicate that leaf mould also has the potential for use in this way. The optimum pH for the process was found to be 2·0, with the kinetics following a second-order reaction rate. Intraparticulate diffusion was not a rate-determining step at this pH.
