Removal of copper ions in polluted waters by DTC heavy metal chelator(DTC类重金属捕集剂对Cu2+去除的实验研究)
, 2014 以乙二胺、氢氧化钠、二硫化碳等为原料，在常温下合成一种橘红色的液体产品DTC-E，经测定，其主要有效成分为二硫代氨基甲酸盐(DTC类).以模拟含铜废水为处理对象，系统考察了反应体系各因素对DTC-E捕集去除游离态Cu2+效果的影响，并将其应用于实际电镀含铜废水的处理以进行验证.研究结果表明，DTC-E对反应体系的pH值适用范围(4~12)较广；最佳反应pH值和DTC-E投加量分别为8.0和1.0倍化学计量比(DTC ：Cu2+);絮凝剂的存在能够显著增强DTC-E对游离Cu2+的捕集去除效果；相比之下 ...

International Journal of Cancer, EarlyView.ABSTRACT Ductal carcinoma in situ (DCIS) is usually detected with mammography screening and assumed to be a precursor of invasive ductal cancer (IDC) of the breast. Yet, despite an approximately 10‐fold increase in the rate of DCIS detection and treatment within 20 years following implementation of mammography screening in the United States, IDC ...
