The acid content of aqueous acidic hydroxylamine salt solutions is reduced by electrolysing the solution in the cathode compartment of a divided electrolysis cell in which the cathode and anode compartments are separated by an anionic membrane and using an aqueous acid as the anolyte....
The water-soluble salt is preferably an inorganic salt, normally possessing not more than a single hydrated species when present as a crystalline solid in water at a temperature of from 10 to 40° C. in an amount in excess of that required to form a saturated solution. Exemplary inorganic ...
Method for removing acid from hydroxylamine salt solution containing excess acidPURPOSE: To obtain a high purity hydroxylamine salt solution by separating an anode solution chamber and a cathode solution chamber with an anionic membrane and by feeding an aqueous solution containing an acid and water ...
Therefore, addition of a mineral salt increases the ionic strength of the solution such that a diffuse layer of counterions will shield carboxylate groups the formerly dissociated in the solution [60]. 3.3. Effect of Rhamnolipid Concentration The impact of RL concentration on the efficiency of ...
Brassinosteroids also increase the activity of some antioxidant enzymes, which allows the removal of excess reactive oxygen species. In addition, BRs can stimulate the synthesis of phytochelatins that bind metal ions into complexes. Brassinosteroids play an important role in inducing plant defense ...
METHOD FOR REMOVING ACID FROM HYDROXYLAMINE SALT SOLUTION CONTAINING EXCESS ACIDPURPOSE: To obtain a high purity hydroxylamine salt solution by separating an anode solution chamber and a cathode solution chamber with an anionic membrane and by feeding an aqueous solution containing an acid and water ...
Process for removing acid from a hydroxylamine salt solution containing excess acidA process is described for reducing the acid content of a solution comprising a hydroxylamine salt and an acid. In one embodiment, the process comprises the steps of:(A) providing an electrolysis cell comprising an ...
In a process for manufacturing food-grade caustic such as sodium hydroxide wherein hydrazine or a derivative or salt thereof is used as a corrosion inhibitor, residual hydrazine is removed from the concentrated caustic product solution by oxidation. The oxidation of residual hydrazine is accomplished ...
