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)
Zhejiang Daxue xuebao. Lixue ban, 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 ...

萌育对芝麻籽粒含氮物质的影响Effect of germination on nitrogen-containing substances in sesame seeds
Zhongguo youzhi, 2022 为探究芝麻籽粒萌育过程中含氮物质的变化，采用去离子水、0.5%氯化钙溶液、1%氯化钙溶液对芝麻籽粒浸泡30 min，然后在30 ℃下进行萌育处理，测定芝麻籽粒萌育0～72 h 期间粗蛋白质、可溶性蛋白质、游离氨基酸、蛋白质水解度以及蛋白质分子质量的变化。结果表明：萌育过程中，粗蛋白质含量先减少后增加再减少；可溶性蛋白质含量在0～4 h略微增加，随后下降，72 h时降低了约25%，3种浸种处理方式变化趋势一致；游离氨基酸含量和蛋白质水解度逐渐增大，3种浸种处理方式游离氨基酸含量有显著性差异；SDS ...
