High concentrations of heavy metals in the soil have detrimental effects on ecosystems and are a risk to human health as they can enter the food chain via agricultural products or contaminated drinking water. Phytoremediation is the direct use of living plants for in situ remediation of metal contaminated soil, sludges, sediments and ground water through contaminant removal, degradation or cont...

Heavy metals pollution has become a more serious environmental problem in the last several decades as a result releasing toxic materials into the environment. Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical processes were used for the treatment of domestic, industrial and agricultural effluents. The commonly used conventional biological treatmen...

One of the new methods used to remove contaminants from effluent is electrocoagulation method, which sometimes combined with other increase removal efficiency contaminants. To simultaneously nickel, cyanide, zinc, and copper, method photo-electrocoagulation was along an oxidizing agent, namely hydrogen peroxide (Hp). In addition, effects factors affecting were studied, including pH, electrode a...

Three marine bacteria, Pseudomonas putida PTCC 1664, Bacillus cereus  PTTC 1665 and Pseudomonas pseudoalkaligenes PTCC 1666 isolated from the East Anzali wetland sediments of the Caspian Sea, were resistant to heavy metals of Cadmium (Cd), Nickel (Ni) and Vanadium (V). Pseudomonas pseudoalkaligenes PTCC 1666 was found to be resistant to all 3 metals Ni, Cd, V. Heavy metal uptake was determined ...
