Ion exchange equilibrium of neutral amino acids on 732 strong acid cation exchange resin in non buffer systems were studied and an equilibrium model was proposed.
研究了非缓冲体系中性氨基酸在732型强酸性阳离子交换树脂上的离子交换平衡，并提出了平衡模型。

The pickled pelt or bated hides were pretreated separately with glyoxylic acid, amino compounds and dicyandiamide resin etc. , then tanned with less chrome.
用氨基化合物，乙醛酸和双氰胺树脂等分别处理浸酸裸皮的软化裸皮后进行少铬鞣制。

Attaching aminoacid to the resin is the sticking point in the whole synthesis, because it has the most important effects on the yield and purification of ultimate product.
