摘 要：通过浮选实验、红外光谱测定，考察了脆硫锑铅矿、磁黄铁矿和铁闪锌矿在丁黄药作用下的浮选行为和巯基类小分子有机抑制剂对三种矿物的抑制效果以及Cu2+离子对巯基化合物抑制效果的影响。

U 2+, Co 2+ and Mn 2+ whose concentrations were 40, 40, 20μg·L -1 respectively could increase the AKP activity significantly in mysis, but higher con...

o2 +在 2 0μg·L-1时明显提高两种酶的活性。而Ni2 +只使两种酶活性降低。鉴于碱性磷酸酶和ATPase与生长发育直接相关，金属离子对对虾幼体生长的影响与对两种酶活性的影响基本一致，因此体内这两种酶活性的高低可作为判别环境因素是否适合对虾幼体生存的指标。
