实验室废弃玻璃作为一种化学试剂在火试金分析中的应用

本文充分调查了废弃玻璃的回收与利用情况,以实验室废弃玻璃的性质为基础,提出了将实验室废弃玻璃应用到分析铅阳极泥和铅精矿中金、银含量的观点,并进行了相关的试验研究,实验样品包括铅阳极泥和铅精矿。通过对实验结果的分析,确定了实验室废弃玻璃替代二氧化硅作为一种化学试剂用于铅阳极泥和铅精矿中金、银含量的试剂用量,保证了分析结果的准确性满足标准方法所规定的精密度要求范围。

Application of Waste Glass in Laboratory as A Chemical Reagent in Fire Assay

In this paper, the recovery and utilization of laboratory waste glass are fully investigated. Based on the chemical properties of laboratory waste glass, we proposed the view of Applying the waste glass produced in laboratory to fire assay to determine the content of gold and silver in lead anode mud and lead concentrate. Concurrently the experiment was carried out. The experimental samples include lead anode mud and lead concentrate. Through the data analysis, we determined the amount of waste glass in laboratory instead of silica as a chemical reagent in Fire assay method to determine the content of gold and silver in lead anode mud and lead concentrate. The accuracy of the analysis results were ensured, and the require?ments of precision by standard methods were satisfied.
