采用光化学反应研究了铜渣中Cu和Fe的溶解行为。实验采用石英玻璃夹套,在玻璃反应釜中间歇进行,在反应釜下埋入紫外线灯,并采用玻璃管作为送风装置。研究了不同波长UVA(365 nm)、UVB(311 nm)、UVC(254 nm)和真空UV光(185 nm)在浸出液中的行为。所有实验在相同条件下,在有和没有紫外线灯的情况下进行比较。研究了自由基形成机制对浸出环境的适应性及其在氧化溶液介质浸出中的可用性。在紫外光(185 nm)和非紫外光条件下,铜的提取率分别为85.1%和70.7%。综上所述,在紫外(185 nm)光反应器体系中,铜渣在最佳条件下的金属溶解率比无紫外光反应器体系效率更高。光化学反应器是使其适应湿法冶金应用和检验工艺的新途径。

Phosphorus fertilizers from less pure sedimentary sources become increasingly important, due to depletion of phosphorus from igneous rock of high quality. Consequently, robust methods with potential to remove various types of hazardous elements are required. Among such impurities, hexavalent chromium (Cr(VI)) is very likely to become a future challenge. Different industrial ways to treat phosphate rock are currently being practised, and we have here studied how chromium behaves when using the nitro-phosphate process. The reduction mechanism of Cr (VI) in nitric acid and phosphoric acid solutions was investigated by measuring redox potential and UV-VIS spectra. The results show that Cr (VI) is not stable in strong nitric acid solutions. Reduction of Cr (VI) species decreased with decreasing temperature, NO2 concentration, ionic strength and absence of light. These findings support the proposed reduction reaction:The reduction rate was observed proportional to the nitric acid decomposition: .
