【摘要】：以活性炭為載體,Fe、Cu為催化劑,催化氧化浸金廢水中的SCN~-,考察了活性炭的性能、催化劑種類、浸漬濃度、pH、溫度等因素對氧化效果的影響;通過XRD考查了催化劑負載在活性炭上的特征。實驗結(jié)果表明,椰殼炭浸漬在0.25mol/L硝酸銅24h,浸漬催化劑在105℃下焙燒24h;干燥后的催化劑在pH 6~7、20~30℃催化氧化500mL 40mg/L的硫氰酸鉀2h,催化氧化活性最好,對SCN~-的去除率可達90%。
[Abstract]:The activity of activated carbon, the type of catalyst and the pH value of the impregnation concentration were investigated by catalytic oxidation of SCN- in gold leaching wastewater with activated carbon as the carrier. The effect of temperature and other factors on oxidation effect; The characteristics of activated carbon supported on the catalyst were investigated by XRD. The experimental results showed that the coir carbon was impregnated at 0.25 mol / L copper nitrate for 24 h, and the impregnated catalyst was calcined at 105 鈩，
