固体废物浸出液中钼含量的测定方法
Determination of Molybdenum in Solid Waste Leaching Liquors
摘要:
建立一种石墨炉原子吸收光谱法测定固体废物浸出液中钼含量的方法。采用硫酸硝酸浸出法制备固体废物浸出液，通过优化灰化温度和原子化温度对方法进行了优化，通过实际样品检测验证了方法的可行性。该方法快速、灵敏、简便，检出限为0.3 μg/L，加标回收率为94.0%~104.0%，相对标准偏差(RSD)为6.83%~8.82% (n = 6)，可用于固体废物浸出液中钼的测定。
Abstract:
Graphite furnace atomic absorption spectrometry was applied to determine molybdenum in Solid Waste Leaching Liquors. Solid waste leaching liquors was prepared with sulphuric acid & nitric acid method. Factors optimized to improve the performance of the determination include ashing temperature and atomization temperature. The developed method was validized by applying it to actual samples. The experimental results showed that the method was fast, sensitive and simple. The detection limit was 0.3 μg/L, the spike recovery ranged from 94.0% to 104.0% with RSD of 6.83% - 8.82% (n = 6). The method can be used to determine molybdenum in Solid Waste Leaching Liquors.
