Abstract
Antimony (Sb) is a toxic and potentially carcinogenic metalloid element. The toxicity of Sb in the environment strongly relies on its speciation. It is necessary to investigate the speciation and content of antimony in soil in order to understand better the real risk associated with Sb in the environment. This study developed water bath heating and soaking-AFS methods to determine the available and carbonate antimony in soil. Through analysis and mutual verification experiments in three different laboratories, the repeatability and reproducibility in the precision experiment were less than 3.44, the average recovery rate was more than 98.1%. These methods were accurate, reproducible and effective for detecting the content of available and carbonate antimony in soil.
Highlights
Antimony (Sb) is a kind of metalloid widely existing in nature, which has the characteristics of high toxicity and long-distance migration[1]
In pretreatment of soil samples, microwave digestion, automatic digester digestion, soaking method and water bath heating method were conducted in three laboratories, respectively
Only soaking and water bath heating method were found to work best, and the qualified rate of standard samples reached 93.3%; 10% parallel sample analysis was carried out for actual samples, which were all within the maximum allowable deviation range
Summary
Antimony (Sb) is a kind of metalloid widely existing in nature, which has the characteristics of high toxicity and long-distance migration[1]. In the process of antimony mining and processing, antimony- containing waste will be produced, which causes environmental pollution, and produces serious toxicity to organisms[4,5]. Antimony can be taken up by plants and photosynthetic biofilms and thereby enter the food chains resulting in environmental pollution [6]. Previous studies have shown that the content of antimony in mature leaves up to 150mg/kg will produce toxic effect on plants[7].The toxic effects are as follows: reducing the activity of cell enzymes, affecting the production of reactive oxygen species, inhibiting chlorophyll synthesis, destroying cell metabolism and the dynamic balance of growth system, and producing oxidative stress effect [8].
