Preparation of Liquid Ferrate and the Optimization of Process Parameters

Abstract:

Ferrate is a powerful oxidant and disinfectant that has been proposed for use in drinking water treatment for more than a decade. The main obstacles in the application are costs and stability. In water treatment, using wet oxidation method to prepare liquid ferrate can save production costs. Saturated ferric nitrate solution can get higher efficiency and productivity to generate ferrate. Water quality has no obvious effect on the productivity of ferrate. The optimum alkaline concentration is 10-13 mol/L. The reaction time and temperature affect the quality of liquid ferrate product. The larger the mole ratio of sodium hypochlorite to ferric nitrate is, the greater the productivity of ferrate is. The proportion of sodium hypochlorite to ferric nitrate should be adjusted appropriately.
