Removal of some heavy metals from wastewater using planiliza abu 65 gm waste remains

Abstract

Wastewater samples were collected from the sewage treatment plant in the Azdinawiya City, south of Nasiriyah district, and fish samples were collected from the Euphrates River in Suq Al-Shuyoukh district, where three types of fish were collected, each with two different weights Planiliza abu 65 gm, heavy metals were measured directly after sampling (Zn, Cd, Cu and Pb) by automatic instrument. A powder was made of fish scales and bones. The scales and bones were ground after cleaning. The scales were filtered by three types of sieves ( 250µm, 1mm and 2.36 mm). The chemical elements were measured by a scanning electron microscope before and after adsorption. The scales and bones adsorbed the following chemical elements from the wastewater. The ability of fish scales and bones powder to adsorption of trace elements from sewage water was tested, where 50 gm of fish scales and bones powder was placed in a burette and its adsorption capacity was tested in five times (zero time, 12 hours, 48 hours, 72 hours and 96 hours). The current study was showed that fish scales have more ability to adsorb trace elements in wastewater from the bones.
