Thermodynamic analysis of pollution and treatment of organic matter in water

Abstract

The problem of environmental pollution is becoming more and more serious with the rapid development of industry and economy, especially the organic matter pollution in water. Thermodynamic analysis method is used based on this to analyze and study the pollution and treatment process of water organic matter in this paper. By proposing that the pollution essence is caused by the uneven distribution of sub-energy, the effect of organic pollutants treatment in four kinds of water bodies in Shenzhen City was analyzed by graphite material adsorption from the perspective of thermodynamic analysis. The experimental results show that the degree of organic pollution in the Jia reservoir of Shenzhen City is from high to low: Dasha River, campus pond, Jia reservoir, and B reservoir. When the ionic strength is 0.04 M, pH is 3.0, graphene loading is 2.5%, and reduced graphene oxide dosage is 200 mg/L, the degradation efficiency of organic pollutants in water is as high as 96.25%.

Greening the waves: experimental and chemometric approaches in spectroscopic methods for organic pollutant determination in natural waters

“…Studies have utilized various methods, including the evaluation of water quality using algal genus characterization, water evaluation indices, and multivariate analysis to assess the level of organic pollution in rivers and other water bodies. 4 Additionally, the presence of organic priority pollutants in runoff has been reported, highlighting the widespread nature of the issue. Green analytical chemistry represents a paradigm shift in the field of analytical chemistry, focusing on the development and application of sustainable and environmentally friendly analytical methods.…”
