先用高氯酸将固体混合物溶解形成水溶液，然后以钍试剂为指示剂，用高氯酸钡溶液滴定溶液中的微量硫酸根，并用EDTA法以钙红为指示剂滴定溶液中的钙离子，从而可以计算出钙基脱硫剂的固硫率(表示为脱硫后固体混合物中的钙硫化)。

When hexanoic acid and heavy metal ions coexist in the solution,the adsorption of metal ions by clay tends to decrease because of the competitive adsorption of hexanoic acid.

当溶液中己酸和重金属共存时，由于竞争吸附使得粘土对重金属的吸附能力普遍有较小幅度的下降；当溶液中存在腐殖酸和重金属共存时，粘土对重金属的吸附能力增强，主要是由于酸性条件下富里酸发生解离后与重金属络合，其络合物与粘土颗粒有一定的结合能力，增强了粘土对重金属的吸附能力。

Based on research results on anodic and cathodic process, mixed-potential models of gold dissolution in the presence of heavy metal ions have been constructed. A Viewpoint is proposed that only being associated with cathodic enhancement by using assistant such as hydrogen peroxide do heavy metal ions enhance gold dissolution in cyanide solutions to the greatest extend.

在详细研究了重金属离子存在条件下金的阳极溶解和氧的阴极还原行为的基础上，构造了重金属强化氰化溶金的混合电位模型，提出了只有在辅以阴极强化的条件下，重金属离子才能最大限度强化金的氰化溶解的观点。
