removal of heavy metal ions from wastewaters a reviewmar 01, · the removal efficiency was above 99.9% when the distance between the electrodes was 3 cm, the current density ranging from 2.5 adm 2 to 3.5 adm 2 and ph of the hg 2+ solutions from 3 to 7. Ölmez (09) studied the performance of ec to remove hexavalent chromium having a high cr(vi) concentration of 70 mg/l.industrial wastewater treatment industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable byproduct. after treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. some industrial facilities generate wastewater that can be treated in sewage treatment plants.
benzonitrile c6h5(cn) pubchembenzonitrile may enter the human body by ingestion, absorption through the skin, or inhalation. the earliest symptoms of cyano compound intoxication may be weakness, headaches, confusion, and occasionally nausea and vomiting.drinking water contamination and treatment techniquesaug , · water is of fundamental importance for life on earth. the synthesis and structure of cell constituents and transport of nutrients into the cells as well as body metabolism depend on water. the contaminations present in water disturb the spontaneity of the mechanism and result in long/shortterm diseases. the probable contaminations and their possible routes are discussed in the present reviewcyanide poisoning in animals toxicology merckremoval from the source of exposure is the main clinical priority in chronic cyanideassociated toxidromes. prognosis for cases of chronic cyanide poisoning other than those associated with thyroid syndromes is guarded.
