Determination of transport parameters of soils around Solt

Absztrakt

A complex labor investigation was performed to determine the adsorption properties of soils around Solt. After collection of samples firstly the soil type was determined as a pre-information of adsorption tests. Two type of test were performed to know the adsorption performance of soils: batch test and breakthrough curve test. In both investigation two type of soil (SD, SV) and two type of heavy metals were investigated. In batch test the Langmuir and the Freundlich isotherms were used to determine the adsorption constants. According to our results the fitting of Freundlich isotherm was better for both soil, and the adsorption of Mn (K_f,SD=2.28, K_f,SV=1.74) was more intensive than Zn (K_f,SD=1.27, K_f,SV=0.84). After performance of static adsorption test, dynamic adsorption test, breakthrough curve test was also performed. The characteristic of adsorption was the same like in case of batch test. The value of distribution coefficient was higher in case of soil SD, and the adsorption was more intensive for Mn.
