1.The conversion film is probably constituted of amorphous and pored alloying tannate chelate.
这种转化膜很可能有一定孔隙的非晶态合单宁酸膜层构成.
2.In this paper, the new chelating resin (PSIM) with a polythioether backbone bearing imidazole group is first synthesized by the reaction between polychloromethylthiirane and imidazole.
通过氯丙烷与咪唑进行高分子反应,合成了以醚为主链、侧链带有咪唑基团的螯合树脂(简称PSIM)。
3.According to the problems in dyes production,the role of cupric ion in coupling-cupric complexation was discussed,and the chelated forms of formazane reactive dyes were introduced.
4.3, A chelating agent which forms an easily water-soluble metal chelated compound such as nitrilotriacetate (NTA) or ethylene diamine tetraacetate (EDTA) is incorporated in a detergent composition.
