云南上蒜磷矿的酸分解反应活性

本文测定了上蒜磷矿与摩洛哥磷矿在柠檬酸及几种无机酸中的分解率,对这两种磷矿的酸分解反应活性进行了比较。又分别测定了这两种矿的组成、红外光谱、二氧化碳指数、晶格常数和比表面积等。证明由于上蒜磷矿比摩洛哥磷矿的二氧化碳含量低,引起其晶体结构的形变较小,孔隙率较低,比表面积较小,致使其酸分解反应活性比摩洛哥磷矿低。

The Reactivity in Acidic Solution of Shangsuan Phosphate Rock in Yunnaan

In this paper, we have determined the decomposition ratio of the Shangsuan and Morocco phosphate rocks in citric and some mineral acids, and have compared the reactivities in acidic solution of the two phosphate rocks. We have also determined the chemical compositions, infra red spectrum, CO2 indexes, lattice constants and specific surfaces etc. Of the two phosphate rocks and have shown that the CO2 contained in Shangsuan phosphate rock is less than that in Morocco phosphate, which brings about less lattice deformation, less voids the ratio and less specific surface. As a consequence of that, comparative reactivity in acidic solution of Shangsuan phosphate rock is less than that of Morocco phosphate rock.
