Abstract In order to explore the application of Cd²⁺ adsorption on yellow brown soils with the best modification ratio of adsorption of Cd²⁺ on bentonites, we prepared two series of yellow brown soils, modified by dodecyl dimethyl betaine (BS-12) and sodium dodecyl sulfonate (SDS), respectively. The structures of soils were characterized by X-ray diffraction and organic carbon contents. The adsorption properties and influence factors, such as ionic strength, pH and temperature were investigated. Furthermore, we also assessed the differences in Cd²⁺ adsorption between bentonites and two modified yellow brown soils. Compared with unmodified soils, the interlayer spacing in modified soils was not significantly changed and the total organic carbon content increased with increment of the total modification. Similar with bentonites, the adsorption of Cd²⁺ on co-modified yellow brown soils was stronger than that of BS modified soils and non-modified soils. At 30oC, the adsorption capacity was 215BS + 322SDS (215%BS-12 + 322%SDS) > 215BS (215%BS-12) > CK1 (soil containing montmorillonite content of 43%) and 33BS + 49SDS (33%BS-12 + 49%SDS) > 33BS (33%BS-12) > CK2 (soil containing montmorillonite content of 6%). In addition, the desorption of Cd²⁺ on co-modified yellow brown soils was higher than CK and BS modified yellow brown soils. Langmuir equation was suitable to describe the adsorption of Cd²⁺ on yellow brown soil. Cd²⁺ could be effectively adsorbed by yellow brown soils with the best modification ratio of bentonites. The adsorption of modified yellow brown soils decreased with ionic strength rising. pH had little influence on Cd²⁺ adsorption. Similar with modified bentonites, the temperature effect changed from positive on CK and amphoteric soils to negative on BS+SDS soils after SDS modified. CEC contributed most to the adsorption difference of Cd²⁺.
