硫化汞
5.a heavy reddish mineral consisting of mercuric sulfide; the chief source of mercury.
6.A heavy reddish mercuric sulfide, HgS, that is the principal ore of mercury.
7.Thus, such phenomena as vermilion turning black, aging of red lead and the fading of arsenic can now be more essentially represented by the chemical reactions of cinnabar having its crystal lattice transformed, lead tetroxide turned into lead dioxide, and arsenic sulfide turned into arsenic oxide.
8.When the titration to Hg~(2+),using HAc-NaAc buffer and KNO_3 as TISAB, chlorine ion selective electrode as indicating electrode,SCE as reference electrode and KBr solution as titrant,reaches 286 mV(vs.SCE),the content of mercuric sulfide is calculated by means of standard curve method.
9.The Reaction of Bis(O,O Diethylthiophosphoryl)Disulfides with Mercuric Chloride
10.Total mercury(expressed as THg) in sediments, mercury adsorbed onto hydroxides of iron and manganese(expressed as Hg-oxal), associated to organic matters(expressed as Hg-H_2O_2), and mercury existed in the crystallized sulphides (expressed as Hg-pyrite) in winter were extracted by a sequential extracted procedures, and then were analysed;
