| Abstract |
Japan Environmental Agency announced 14 kinds of endocrine disruptors was detected on 130 watersheds of Japan in 1998 and the Ministry of Environment of Korea announced 13 kinds of endocrine disruptors involving Bisphenol-A was detected in domestic watersheds in 2000. According to the report, bisphenol-A, nonyiphenol and 4-n-heptylphenol were detected in all domestic watersheds. This study was carried out for finding removal method of 13 species of endocrine disruptors on water treatment processes. The concentrations of prepared endocrine disruptors standard water were about 10 ㎎/L and we analyzed the concentration of endocrine disruptors by W Absorbance. All 13 pieces of endocrine disruptors could be absorbed into the powder activated carbon(PAC) and the phthalates(DBP, DEP, DEHP) could be coagulated but other endocrine disruptors could not be coagulated by coagulant. Ozonation showed that it could not remove endocrine disruptors by measuring W Absorbance, but other researchers reported ozonation could transfered endocrine disruptors to isomer. |
