1. INTRODUCTION Water is the most important and essential component on the earth for
vital activities of living beings. Unfortunately, water quality of our water resources is …

Fluoride contamination in drinking water due to natural and anthropogenic activities has
been recognized as one of the major problems worldwide imposing a serious threat to …

Chitin, the second most important natural polymer in the world, and its N-deacetylated
derivative chitosan, have been identified as versatile biopolymers for a broad range of …

Chitin and chitosan-derivatives have gained wide attention as effective biosorbents due to
low cost and high contents of amino and hydroxyl functional groups which show significant …

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 performance and adsorption mechanism of a high capacity hydrous
zirconium oxide adsorbent were investigated. Fluoride adsorption on the hydrous zirconium …

Nano hydroxyapatite (Ca10 (PO4) 6 (OH) 2, HAp) has aroused widespread attention as a
green and environmentally friendly adsorbent due to its outstanding ability in removing …

Fluoride is an essential element, indispensable for maintenance of dental health.
Nevertheless, fluoride concentrations in drinking water above 1.5 mgL− 1 may be …

In this research work, pumice that is functionalized by the cationic surfactant,
hexadecyltrimethyl ammonium (HDTMA), is used as an adsorbent for the removal of fluoride …

The state-of-the-art on calcium orthophosphate (CaPO4)-containing biocomposites and
hybrid biomaterials suitable for biomedical applications is presented. Since these types of …
