In this study the trapping capacity of synthetically prepared goethite (a‐FeOOH) in the removal of Cr3+, Cd2+ and Pb2+ (10–4 M) in varying ionic strength conditions of the medium was determined. The adsorption study was carried out in the pH rang

This work presents the data on fluoride adsorption by goethite at varying pH (4.00–10.00), ionic strengths (0.05M‐0.1M) and concentrations of a competing ion (iodide). The triple layer surface complexation model(TLM) was shown to be able to descr

Fluoride ion interaction with synthetically prepared goethite has been investigated over a range of pH values (4–9) and F− concentrations (10−3−10−5 M). The amount of F− retained by goethite suspensions was found to be a function of pH, m
