Abstract
Molybdenum is an essential trace element for plants and animals. Its deficiency causes serious health problems. The behavior of molybdenum varies with redox conditions. The molybdenum isotopic composition is thought to be a unique geochemical tool for indicator of paleoredox conditions. Although the biogeochemical behavior of molybdenum in the surface conditions is important, the elementary reactions affecting the behavior are currently lucking. The concentration and mobility of trace elements at surface condition is governed by adsorption reactions on mineral surfaces. In present study, we analyzed the published adsorption data of molybdate on oxides by means of surface complexation modeling to understand the elementary reactions of molybdenum adsorption behavior.
