Monitoring of Heavy Metal Pollution in Soil Environment Based on Spectral Analysis

研究基于光谱分析的土壤环境重金属污染监测方法,解决土壤环境中重金属污染监测困难的问题。利用对角线法采集土壤样本,对土壤样本进行风干等预处理,将预处理后的土壤样本放置在激光仪中获取光谱数据,通过边界值判定对光谱数据进行平滑降噪处理,建立回归线性定量分析模型,分析光谱特征,得到土壤环境重金属污染的监测结果。结果:通过基于光谱分析的土壤环境重金属污染监测对土壤样本进行监测,得到土壤中的重金属污染包括铁、锌、锰、镉、镍、汞、钴等,监测精度较高。

This study analyzed the monitoring methods for heavy metal pollution in soil environment based on spectral analysis to solve the problem of difficult monitoring of heavy metal pollution in soil environment.Using the diagonal method to collect soil samples,pre-treatment such as air drying is carried out on the soil samples.The pre processed soil samples are placed in a laser instrument to obtain spectral data,and the spectral data is smoothed and denoised through boundary value judgment.A regression linear quantitative analysis model is established to analyze spectral characteristics and obtain monitoring results of heavy metal pollution in the soil environment.Through the monitoring of heavy metal pollution in soil environment based on spectral analysis,it was found that the heavy metal pollution in soil includes iron,zinc,manganese,cadmium,nickel,mercury,cobalt,etc.,with high monitoring accuracy.
