Abstract:
Pollution by toxic chemicals that are resistant to biological degradation and have potential for accumulation in biological organisms is becoming world-wide problem. Organic phosphate esters (OPEs) are widely used plasticizers, industrial hydraulic fluids, and lubricant additives. Various OPEs have been detected in environmental samples and in industrial and domestic wastewaters. Ultraviolet (uv) irradiation is known as effective treatment for persistent chemicals in natural water or wastewater. in order to removal of OPEs in water, some fundamental experiments with UV irradiation were performed with a mercury lamp, and photochemical behaviors and photodecomposition products were examined for seven OPEs namely (tributyl phosphate (TBP), tris (choropropyl) phosphate (TCPP), tris (choroethyl) phosphate (TCEP), trioctyl phosphate (TOP), tris (dichoropropyl) phosphate (CRP), triphenyl phosphate (TPP), and Tricresyl phosphate (TCP).
