WebJun 1, 2004 · Abstract. In order to assess the adsorption of iodate by different soils from China, a series of batch experiments were conducted. It was found that soils rich in iron oxide had high affinity for iodate. Iodate adsorption isotherms could be well fitted with both Langmuir and Freundlich equations. Iodate adsorption by 20 different soils from ... WebA method is described for the removal of "free" iron oxides from soils and colloidal clays which employs the principle of microbial reduction and subsequent solution. 2. The effectiveness of this method was determined by comparing it with the chemical method described by Truog, et al., and with the untreated colloidal clays. 3.
