前言 碱性锌锰电池中负极粘合剂的主要作用为：（1）作为锌粉分散剂，使锌膏在电池贮存与放电过程中不发生固液分离；（2）固定负极区的碱液，使碱液不被或少被正极或隔膜吸收。

NOVELTY - Alkali chemicals are added to the cyanogen group gold-containing liquid, to obtain an alkaline liquid. Zinc is added to the alkaline liquid, and the formed deposit is dissolved in aqua regia. A reducing agent is added to the deposit solution and a deposit is produced. Gold is then separated by heat-processing the deposit.

本发明的新颖性在于：将碱性化学物质添加到氰化含金液中，以获取碱液；将锌加入到碱液中，并将形成的沉积物溶解到王水中；然后在沉积溶液中加入一种还原剂，形成新的沉积物；最后通过加热处理沉积物来分离金。

As caustic solution prewashing of FCC gasoline discharges lots of lye, it is nec essary to improve the process. The solid base pretreating of FCC gasoline wil l completely avoid this problem.
