Natural zeolites are abundant and low cost resources, which are crystalline hydrated
aluminosilicates with a framework structure containing pores occupied by water, alkali and …

Excessive intake of fluoride (F), mainly through drinking water, is a serious health hazard
affecting humans worldwide. There are several methods used for the defluoridation of …

The defluoridation capacity (DC) of a chelating resin, namely Indion FR 10 (IND), and
Ceralite IRA 400 (CER), an anion-exchange resin, were compared under various …

Natural, H-form and Pd-containing clinoptilolite and mordenite were characterized using
adsorption, AFM, FTIR, and TG–DTA methods. The initial natural adsorbents have small …

This study describes the advantages of nano-hydroxyapatite (n-HAp), a cost effective
sorbent for fluoride removal. n-HAp possesses a maximum defluoridation capacity [DC] of …

Stilbite zeolite (STI), a natural zeolite with high crystallinity and an open pore system, was
modified with FeCl3 solution for the removal of fluoride from drinking water. The parent STI …

Kaolinite clay obtained from the mines was processed and studied for its fluoride sorption
capacity. The surface area of the clay mineral was increased from 15.11 m2/g (raw) to 32.43 …

Delivering the right amount of fluoride to drinking water protects the teeth from decay and
reduces the risk of cavities. Nonetheless, fluorosis has been diagnosed as the result of …

Adsorption equilibrium and kinetics of fluoride on a sol–gel-derived activated alumina and
its modifications with calcium oxide or manganese oxide were studied to explore the …

The adsorption process, a well-known surface phenomenon, has been commonly applied
for enzyme immobilization for the separation and purification of polluted water resources …
