- In this study, degradated and hydrophilized larch tannin was used to prepare water soluble chelates with iron, mangnese, zinc and copper ions. 落叶松单宁经降解及亲水化处理,与铁、锰、锌、铜离子反应制备出水溶性螯合物。
- At first, the adsorption behaviors of Cd(II) on collagen fiber immobilized black wattle tannin, larch tannin and bayberry tannin were investigated. 首先研究了胶原纤维固化黑荆树单宁、固化落叶松单宁和固化杨梅单宁对Cd(II)的吸附特性。
- Modified larch tannin was prepared by grafting copolymerization and sulfoalkylation, and successfully used as retanning agent, possessing good water solubility and enhanced penetration rate. 利用接枝共聚和磺烷基化的方法对落叶松单宁改性。
- Thus, it can be considered that larch tannin is derived from catechin and its tanning properties should be basically identical with those of catechol tannins and areca tannin. 因此,可认为落叶松单宁中的一部分是以真儿茶素为母体的一种单宁,其鞣革性能基本上应与儿茶单宁及槟榔单宁相同。
