Application of Taguchi design in the removal of heavy metals from Simulated metal solutions using groundnut shell and tea bag as a natural absorbent

Abstract

The percentage of heavy metals removal from the solutions at varying conditions was used to model the effectiveness of the adsorbent. All models and their statistical parameters were reported in the study. The model identified as the best was the one involving the removal of chromium concentration using the tea bag adsorbent. The ability of the model to predict other concentrations which were not used in developing the model was high and was reported as preR2 of 0.94.
