TL;DR: In this article, a three-electrode cell without any diaphragm but with a sandwich bath by galvanostatic electrolysis was used to determine the concentration of ClO2 in the electrolyte.
Abstract: Preparation of chlorine dioxide by electrocatalytic reduction of sodium chlorate with Ti/IrO2 anode and Ti cathode was studied in a three-electrode cell without any diaphragm but with a sandwich bath by galvanostatic electrolysis. Classic iodometry was used to determine the concentration of ClO2 in the electrolyte. The change of space-time yield with current density, the concentration of H2SO4, the concentration of NaClO3, reaction temperature and electrolysis time were studied through single factor experiment in order to determine the optimal conditions of electrolysis. It shows that the optimal conditions of ClO2 preparation by electrocatalytic reduction of sodium chlorate were: i=60 mA/cm2, [H2SO4]=4.5 mol/L, [NaClO3]=1.0 mol/L, T=30 °C, t=30 min. Under these conditions, the space-time yield of ClO2 reached 1.50 mg/L·s.

TL;DR: A process for preparing sodium chlorite includes such steps as dissolving hydrogen peroxide and solid sodium chlorate in water, adding the resultant solution along with sulfuric acid to a ClO2 generator to generate the mixture of ClO 2 and oxygen.
Abstract: A process for preparing sodium chlorite includes such steps as dissolving hydrogen peroxide and solid sodium chlorate in water, adding the resultant solution along with sulfuric acid to a ClO2 generator to generate the mixture of ClO2 and oxygen, loading the mixed absorbing liquid containing sodium hydroxide and hydrogen peroxide into an absorbing tower, adding ClO2 to the absorbing tower while escaping oxygen, and finally generating sodium chlorite. Its advantages are high output rate (more than 95%) and high purity (more than 95%) of product.

TL;DR: In this article, the residual effect of sulphuric acid, copper sulphate, sodium chlorate, barium chlorate and sodium dichromate on three typical Alberta soils was investigated.
Abstract: Experiments were conducted to determine the residual effect of sulphuric acid, copper sulphate, sodium chlorate, barium chlorate and sodium dichromate on three typical Alberta soils. No problem of residual effect was found with the two leaf sprays, sulphuric acid and copper sulphate. Sodium chlorate will remain toxic over a period of about two years, depending mainly on the organic matter content of the soil and the amount of leaching that takes place. The distance that the chlorate will leach down into the subsoil will depend on the amount of rainfall and the character of the soil. As soon as the chlorate is leached out or is reduced the soil returns to its normal productive power. Sodium dichromate decomposes very rapidly in the soil. It has a depressing effect on nitrification and on the activity of the soil micro-organisms. However, there is practically no residual effect from the use of sodium dichromate on soils of medium to high organic matter content.
