ABSTRACT
Use of Regenerated Natural Sand Material as an adsorbent/ion exchanger for the removal of Total Hardness by Batch Mode Adsorption was investigated. Batch Mode Adsorption technique was carried out by varying particle size, initial concentration, contact time, pH, sorbent dosage and temperature. Langmuir, Freundlich and Temkin isotherm models were used to study the adsorption/ion exchange process. The treatment of water for the removal of total hardness was effectively done by using the Regenerated Natural Sand Material and the XRD patterns were used to confirm the study.
Keywords: Water softening, Natural sand in Irumeni, Adsorption/Ion Exchange, Isotherm models.
