Application of modified clays in the removal of phosphates and E. coli from aqueous solution [Elektronski vir]Chauhan, Tanya ...The presence of microorganisms and inorganic pollutants in water bodies results in adverse effects on nature as well as human health. In this study, clay-based adsorbents were used for the removal of ... phosphates and Escherichia coli bacteria. Two samples, Na-Zr-50-2.5 and Na-Zr-50-5, were prepared using 2.5 and 5 mmol of zirconium per gram of clay. The former material has shown better Langmuir phosphate adsorption capacity (∼11.5 mg P/g) at pH 4. Chitosan modification was applied to Na-Zr-50-2.5 to improve its performance at higher pH. Post modification, the maximum adsorption attained at pH 4 was 14.5 mg P/g, and it improved from 8.3 to 11.8 mg P/g at pH 7. The possible major governing mechanism responsible for the adsorption of phosphates was the formation of inner-sphere complexes. Application of Na-Zr-50-2.5 was also explored for removing E. coli cells from aqueous saline solution. The E. coli removal efficiency of this sample was found to be 62.64 %. This study reveals that modified clays effectively reduce the phosphate and E. coli levels in aqueous solution and can be proved as environment-friendly, low-budget adsorbent materials in wastewater treatment.Source: Environmental nanotechnology, monitoring & management. - ISSN 2215-1532 (Vol. 22, [article no.] 100965, Dec. 2024, 11 str.)Type of material - e-article ; adult, seriousPublish date - 2024Language - englishCOBISS.SI-ID - 196894211
