微波消解-分光光度法测定固废中的总磷研究
|
摘要
固体废弃物中含有大量的总磷,会对周围环境及生态环境产生较大的污染,相关部门需要准确测定固废中的总磷含量,有针对性地采取处理措施。基于此,本文首先介绍了固体废弃物的危害、传统总磷测定方法的不足,并提出了微波消解-分光光度法这一全新总磷测定方法;然后选择某一垃圾填埋场的固体废弃物作为实验对象,应用微波消解-分光光度法对其总磷含量进行测定。测定结果显示,微波消解-分光光度法的准确性偏高,可以用于总磷检测。
Solid waste contains a large amount of total phosphorus, which will cause greater pollution to the surrounding environment and ecological environment.Relevant departments need to accurately determine the total phosphorus content in solid waste, and take targeted measures. Based on this, this paper first introduces the hazards of solid waste and the deficiency of traditional total phosphorus determination methods, and proposes a new method for the determination of total phosphorus in microwave digestion-spectrophotometry; then selects solid waste from a landfill. As a subject, the total phosphorus content was determined by microwave digestionspectrophotometry. The measurement results show that the microwave digestion-spectrophotometry method has high accuracy and can be used for total phosphorus detection.
