Introduction & Objective: Industrial wastewaters including heavy metals, are among the important sources of environmental pollution. Heavy metals such as chromium are found in plating wastewater and is harmful for human health and environment. The purpose of the present study was to investigate the absorption of heavy metals such as chromium onto modified holly sawdust as an cheaper absorben...
Backgrounds & objectives: Contamination of the environment by heavy metals, pollute water and agricultural products. The aggregation of these metals will cause various diseases for human. Therefore, it is important to study how to make them safe. The purpose of this study is to evaluate the efficiency of starch-iron oxide nanocomposite in removing two heavy metals, nickel and cadmium, from wast...
Natural occurrence and anthropogenic practices contribute to the release of pollutants, specifically heavy metals, in water over years. Therefore, this leads a demand proper treatment minimize harmful effects toxic metals water, so that supply clean can be distributed into environment or household. This review highlights several methods used removing metal from water. Among various methods, ads...
Elevated concentrations of heavy metals in drinking water resources and industrial or urban wastewater pose a serious threat to human health the equilibrium ecosystems [...]
Heavy metals pose a risk of contaminating groundwater and surface water sources due to geogenic activities, industries and agricultural sources. The removal of heavy metals e.g., cadmium, lead, and zinc from drinking, industrial and irrigation water at low concentrations is a recurring challenge, especially in developing countries. Biosorption is a relatively new process that has proved to be v...
Groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. This study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...
The importance of removal of heavy metals from drinking water has received significant attention of researchers and decision makers across the globe. Bio-adsorbents have emerged as potential remediation materials for the removal of heavy metals and metalloids from both groundwater and surface water. Plants, algae, fungi are some of the biomass derived adsorbents which are capable of removing he...
Shortage of water resources and deterioration of water quality have urged the need to develop new technologies for the removal of contaminants from water. Heavy metals produced by municipal and industrial activities are among the most toxic contaminants present in the natural and waste waters. Different methods have been developed for the elimination of heavy metals from water resources and ind...
Heavy metals and dyes are major contributors in contamination of water streams. These contaminants enter into our eco- system, thus posing a significant threat to public health, ecological equilibrium and environment. Thus a combined discharge of these contaminants results in water pollution with high chemical oxygen demand, biological oxygen demand, color, particulate matter, suspended particl...
