A Study on Biosorbents for the Removal of Chloride Ion from Water - Subhashish Dey - Bog

The presence of pollutants in aqueous solution particularly from hazardous heavy metals and metalloids is an important environmental and social problem. The chlorides are one of the serious groundwater contaminants in rural areas. The chlorides are regulated in drinking water quality primarily because excess amounts can cause disease. Chloride in both its gaseous and liquid form can be irritating to the eyes, respiratory tract and skin due to its alkaline nature. Biosorption is one of the biological treatments that has emerged as a new technology for the removal and recovery of metal ions from aqueous solutions which is more environmentally friendly. In this study biosorption were used with the intention to remove heavy metals such as copper, zinc, chlorides and mercury ions from synthetic (distill) water. In the preliminary water analysis, the results indicated that several factors including Total Dissolved solids (1,07,000mg/l), Total solids (67,500mg/l), Suspended solids (1,81,000mg/l) shows higher value. Every biosorbents had different physical, chemical and biological properties for heavy metals removal by biosorption from the water.
