What is the effect of H3PO4 activation on defluoridation efficiency of activated carbon given that fluorides may exist as fluorapatite (Ca₅(PO₄)₃F)?

10 February 2021 0 10K Report

Fluorides may exist and be removed from ground water in the form of fluorapatite ( Ca₅(PO₄)₃F ). Does using phosphoric acid ( H3(PO₄) activation in the production of activated carbon have an effect on its (activated carbon) defluoridation efficiency?
