Estimation of Se(VI)/Se(IV) ratio in water by the ratio

adsorption on particulate matter in water. Among various elements that form oxyanions, such as sul-fur, chromium, arsenic (As), selenium (Se), mo-lybdenum, and rhenium, Se is unique in terms of having two oxidation states that form oxyanions in natural water. At equilibrium, the concentration ratios of various redox species such as Se(VI) and

Fe speciation was also measured in the soluble fraction of the sample and the results showed the contribution of anthropogenic iron to the collected particles. Lab-created simulated marine particles were used to study the different variables affecting Fe solubility in atmospheric particulate matter during atmospheric transport.
