Investigating the Effect of Soil pH on Sorption of Salinomycin in Clay and Sandy Soils | Chapter 7 | Modern Advances in Geography, Environment and Earth Sciences Vol. 6

 Salinomycin is a polyether ionophore commonly used in chicken to reduce coccidial infections and improve growth. The antibiotic is excreted in large amounts as the parent compound, which eventually ends up in agricultural soils. To further understand the compound's behaviour in the soil environment, researchers must conduct sorption-desorption investigations. Salinomycin sorption was investigated in four agricultural soils at three pH levels: 4, 7, and 9, including a clay soil with low organic matter content (LOM), a clay soil with high organic matter content (HOM), a sandy soil with HOM, and a loamy sandy (LOM) soil. The desorption experiments were carried out using the batch equilibration method. Regardless of soil organic content or pH, all soils were shown to be extensively sorbed by more than 98 percent salinomycin. Salinomycin sorption increased marginally when the pH declined in the sandy soil, while sorption increased marginally in the two clay soils as the pH increased. After 72 hours, salinomycin desorption in methanol was less than 0.2 percent of the amount given, however it was larger than 70% in phosphate buffer (pH 7). Because the phosphate buffer would simulate, to some extent, the quality of water flowing through field soils containing various salts, salinomycin could pose serious dangers to both shallow ground water and surface water bodies.
