Abstract
A method for oxidizing an inorganic species in an aqueous solution comprises the steps of: (i) supplying an oxidizable source of sulphur, and oxygen to the solution; and (ii) irradiating the solution with UV light such that both the inorganic and sulphur species are oxidized.
Claims8
A method for oxidizing selenium, vanadium, nickle, arsenic, manganese, cerium or uranium in an aqueous solution comprising the steps of:
- (i) supplying an oxidizable source of sulphur as a photoabsorber, and oxygen to the solution;
- and
- (ii) irradiating the solution with UV light such that the selenium, vanadium, nickle, arsenic, manganese, cerium or uranium is oxidized.
A method of oxidizing at least one of selenium, vanadium, nickle, arsenic, manganese, cerium and uranium in an aqueous solution, the method comprising the steps of:
- (i) supplying an oxidizable source of sulphur as a photoabsorber to the solution;
- (ii) supplying oxygen to the solution;
- and
- (iii) irradiating the solution with UV light such that oxidation of at least one of the selenium, vanadium, nickle, arsenic, manganese, cerium and uranium occurs.
