Nitrate removal from water using alum and ferric chloride: A comparative study of alum and ferric chloride efficiency

Background: Nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. This study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the conventional coagulation process. Methods: In this research...

Distribution of Cr, Pb, Cd, Zn, Fe and Mn in Lake Victoria sediments, east Africa.

The presence of many metals at trace or ultra-trace levels in the human environment has received increased global attention (WHO 1977; Hutton 1982; IRPTC 1984). Surveillance of concentrations of heavy metals in the environment is of global interest since elements like cadmium, lead and mercury are listed as environmenta]ly dangerous chemical substances. Sediments as a sink for pollutants are wi...

sources of cu, v, cd, cr, mn, zn, co, ni, pb, ca and fe in soil of aradkooh landfill

currently all the waste produced are collected and transferred to the only landfill of tehran,aradkooh (kahrizak), that is located in the south of tehran. this landfill has been in use for over 45 years that has received over 35 million tons of waste during its life. in the present investigation 40 soil samples were collected from aradkooh landfill to know about the origin of metals. the sample...
