The Influence of Biodegradable Polymer Materials on Heavy Metal Activity in Soil Based on Analysis of Big Data
Lili Fu, Ningning Zhou · Journal of Physics Conference Series · 2021
Abstract Biodegradable polymer material is a new type of slow-release organic fertilizer. It contains many nutrients, and has a long degradation cycle. at the same time, It can provide nutrients continuously, and the degradation products are pollution-free, which can significantly reduce the negative impact on the environmental system. According to big data analysis, biodegradable polymer materials can not only provide nutrients during the degradation process, but also solidify heavy metal ions and reduce their activity by increasing soil pH and increasing soil available phosphorus and organic matter content. This article takes biodegradable polymer materials rich in various nutrients as the research object. Through leaching experiments, the environmental impact of biodegradable polymer materials on soil was studied, which provided a theoretical basis for the development of economical and practical chemical remediation techniques for heavy metal contaminated soil[1-2].
