摘要
本文较为系统地评述了邻苯二甲酸酯的环境行为、生态效应、环境归趋、数学模型和处理技术。指出邻苯二甲酸酯是生产量大和应用面广的人工合成有机化学品,是目前世界上全球性的一类环境有机污染物。这类化合物的低水溶度和低挥发性导致了它们的高吸附亲和性,从而使得该类化合物在固体颗粒物表面的行为对于研究它们在环境中各种过程具有十分重要的作用。
This paper reviews systematically environmental behavior, ecological effect, environmental fate, mathematical models, and treatment technology of phthalate esters. It is pointed out that phthalate esters are synthetic organic chemicals produced and used in a large scale. The concentration of them in aquatic environment is about 0.1-1000ppb. They have become a kind of global environmental organic pollutants. The low aqueous solubility and low volatility lead to their strong adsorption affinity. The results show the behavior of phthalate esters on solid particulates surface plays an important part in studying their environmental processes. The treatment technologies in common use for phthalate esters are physical, chemical and biological methods, but biological is more commonly use method.
