This research article deals with an electrosynthesis of hydrous titanium dioxide by anodic dissolution of titanium sacrificial anodes and their application for the adsorption of manganese from aqueous solution. Titanium sheet was used as the sacrificial anode and galvanized iron sheet was used as the cathode. The optimization of different experimental parameters like initial ion concentration, ...

As an efficient method for ammonium (NH4+) removal, contact catalytic oxidation technology has drawn much attention recently, due to its good low temperature resistance and short start-up period. Two identical filters were employed to compare the process for ammonium removal during the start-up period for ammonium removal in groundwater (Filter-N) and surface water (Filter-S) treatment. Two typ...

Batch experiments were conducted to evaluate the ability of steel slag in removing manganese from aqueous solution. Several variables had been setup to evaluate the performance of steel slag to remove manganese from aqueous solution in different experimental condition. The variables include contact time, size, dosage, pH and initial concentration of manganese. The equilibrium contact time was a...

The removal of Mn(II) from coal mine drainage (CMD) by chemical addition/active treatment can significantly increase treatment costs. Passive treatment for Mn removal involves promotion of biological oxidative precipitation of manganese oxides (MnOx). Manganese(II) removal was studied in three passive treatment systems in western Pennsylvania that differed based on their influent Mn(II) concent...

Potassium Permanganate (KMnO 4 ), which is a kind of strong oxidizer, used in water production. As KMnO containing Manganese, the Manganese concentration may get higher by overdosing additives, however, there isn’t any conclusion dosing interval present study. This paper sand as catalyst and trying to determine optimal amount oxidizers, ratio limit. The results showed that could remove manganes...

Arsenic is a kind of protoplasmic poison, which exists widely in the natural environment. Consuming too much arsenic can cause number health problems. Manganese oxide plays an important role pollution removal technology. In this paper, hazard and its treatment methods application manganese oxides are summarized, prospect research on by put forward.
