摘要

Present study on thorium(IV) ions in the Shivnath River basin in Chhattisgarh, India. These samples were analyzed using 3,6-dichloro-2,5-dihydroxy1,4-benzoquinone. Determine thorium(IV) ion concentration using UV–visible spectrophotometry. As per the World Health Organization and Environmental Protection Agency, the permissible maximum of thorium(IV) ions in drinking water is less than 30 μg/l, soil is 6 ppm, and sand is 5–7%. Thorium(IV) concentrations in the Shivanth River ranged from 0.1 to 0.95 ppm. Indian beaches contain 41.3 ppm. This study assessed the contamination factor (1.77), pollutant load index (1.01), geoaccumulation index (−1.536), and enrichment factor (2.35). ANOVA showed thorium(IV) ion mitigation.
