Studies of phosphate anion sorption using the soil samples

The paper presents the results of studies of phosphate anion sorption on various types of soil taken up from the Lublin Province (Poland). Anions belong to the group of ions witch undergo insignificant sorption according to the soil science. As follows from the studies anion sorption depends insignificantly on pH. Sorption isotherms can be described using the Freundlich equation. Sorption extent depends on concentration of iron ions and organic substances in the sample. Specific sorption (chemisorptions) plays the greatest role in the process under investigation. (author)
