为了控制胺类捕收剂对环境造成的污染,借鉴表面活性剂等有机污染物的生物降解性评价体系,采用BOD5/CODCr 法和OECD-301B(ISO 9439)标准对胺类捕收剂的生物降解性进行评价,考察分子结构对生物降解度的影响。研究表明,十二胺、十八胺、癸烷基丙基醚胺(醚胺609)、十二烷基丙基醚胺(醚胺601)、十二烷基三甲基氯化铵、十二烷基三甲基溴化铵28 d最终好氧生物降解率分别为76.0%、50.6%、63.2%、56.3%、63.4%、68.0%,生物降解指数分别为173.4、162.2、160.8、149.4、164.6、171.2,其中癸烷基丙基醚胺和十二烷基丙基醚胺对微生物有抑制作用,其抑制时间分别为2 d和4 d,除癸烷基丙基醚胺和十二烷基丙基醚胺...

The paper is to present our research results on aerobic biodegradability of amine collectors.As is known,amine is a kind of broad-spectrum oxidized ore collector,whose bonded atom is N.Amine is regarded as the alkyl derivatives of ammonium (NH3).The present paper has done a research on the biodegradability of amine collectors by using the methods of BOD5/CODCr and OECD-301B(ISO 9439),in accordance with the testing standards for the biodegradability of surfactants and other organic compounds in hoping to better control the pollution of amine col...
