摘要
本文借助于等离子发射光谱(ICP—AES)和紫外光谱(UV)研究了单宁酸与硅灰石、透辉石矿浆作用的溶液化学。结果表明:矿浆中硅灰石溶解下来的钙离子组分能与单宁酸发生化学反应。揭示了单宁酸对透辉石选择性抑制机理。
The mechanisms of interaction between tannic acid and calcium ions,either addedexternally to or innerently present in the solution(dissociated from mineral surface,are studied by theuse of Inductively Coupled Plasma Atomic Emission Spectroscopy(ICP—AES),UtravioletSpectroscopy(UV).It is found that wollastonite has a high solubility in the concentration of calciumions,calcium ions are able to interact with tannic acid.
