Isothermal Modelling of the Adsorption of Lead (II) Onto Activated Carbon from Tridax procumbens

Hypertension and kidney damage have been linked to lead exposure in adults. Any person can be harmed by lead, but pregnant women their unborn children are especially vulnerable. Presently, pollution is removed using membrane separation, ion exchange, precipitation, biosorption. Biosorption's low operating costs, high efficiency at detoxifying concentrations of toxicants, small volume disposal materials make it the least problematic these technologies. The biosorption (II) onto activated carbon from Tridax procumbens remodeled nonlinear regression optimal mode was determined a series error function assessments. Freundlich model performed best statistical tests including root-mean-square (RMSE), adjusted coefficient determination (adjR2), bias factor (BF), accuracy (AF), corrected Akaike Information Criterion (AICc) calculated parameters kF value 1.334 (1/g) (95% confidence interval 0.821 1.847) nF 3.872 C.I. 1.972 5.771). Modelling approach allows for calculation uncertainty range terms 95% that would useful comparison discriminant future studies
