Effect of Environmental Conditions on Strontium Adsorption by Red Soil Colloids in Southern China

The fate of radionuclides in the environment is attracting increased attention. effect various environmental effects on adsorption behavior strontium ion (Sr2+) by red soil colloids Southern China was studied a series batch experiments, and mechanism briefly investigated as well. With increase solid–liquid ratio concentration Sr2+, efficiency gradually. pH ionic strength strong, while temperature had little effect. data fitted to Langmuir model indicates that process monolayered homogeneous. thermodynamic parameters also show Sr2+ spontaneous exothermic process. aim this work gain insight into role field.
