Definitions
- the first object of the invention is therefore the use of a composition comprising at least one polysaccharide for purifying a water loaded with metals.
- the polysaccharide is chosen from the group comprising cellulose, starches and vegetable gums.
- natural flour rich in starch can also be used, such as cereal flour such as wheat, corn, or potato starch.
- the cationic modified polysaccharides used in the invention can be obtained by customarily reacting the polysaccharide raw materials mentioned above.
- the introduction of cationic or cationizable groups into the polysaccharide may be carried out by a nucleophilic substitution reaction.
- the introduction of cationic or cationizable groups into the polysaccharide can also be carried out by a radical polymerization comprising the grafting of monomers comprising at least one cationic or cationizable group on the polysaccharide.
- R 4 represents a hydrogen atom or an alkyl group having from 1 to 20 carbon atoms
- counterions can be chosen from chloride ions, bromides, iodides, fluorides, sulfates, methylsulfates, phosphates, hydrogenphosphates, phosphonates, carbonates, hydrogenocarbonates, or hydroxides.
- counter-ions selected from hydrogenophosphates, methylsulfates, hydroxides and chlorides are used.
- the degree of substitution of the cationic modified polysaccharides used in the invention is at least 0.01 and preferably at least 0.1. If the degree of substitution is less than 0.01, the efficiency of carrying out the removal is reduced. If the degree of substitution exceeds 0.1, the polysaccharide inevitably swells in the liquid. In order to use a modified polysaccharide substituted at a level greater than 0.1, it is preferable to modify it to make it insoluble. These changes are described later.
- the supernatant is removed by suction using a cane with filter tip, then reintroduced 600 ml of demineralized water into the reactor.
- the solid + liquid mixture is then filtered on No. 3 frit.
- the cake is taken up in a liter of demineralised water heated at 70 ° C. with vigorous stirring for 2 hours, at the end of which the stirring is stopped and decanted.
- the supernatant is removed by suction using a filter nozzle cane.
- the washing operation by redispersion in 1 liter of demineralized water, decantation and removal of the supernatant is repeated 4 times with cold water. At the end of the last washing, the decanting solid is separated and then frozen and dried by lyophilization.
- the arsenic assays are performed by ICP / MS (Inductively Coupled Plasma / Mass Spectrometer) with an uncertainty of 10%.
- the samples to be analyzed are acidified immediately with nitric acid after collection and then stored in the refrigerator in polyethylene bottles.
- An arsenic stock solution (V) of concentration 500 mg / l is prepared from arsenic oxide As 2 O 5 . Girls solutions, with a concentration ranging from 1 to 50 mg of As / l, are prepared just before use by dilution of the stock solution.
- the starch A is injected into a 150 ml pyrex beaker at 100 ml of the solution to be treated.
- the pH of the suspensions is adjusted to pH 7 with concentrated NaOH and HCl solutions.
- the supernatants of the suspensions are recovered by filtration for determination of their residual arsenic content.
- This test demonstrates the effectiveness of crosslinked cationic starch to remove As (V) at neutral pH and at a temperature of 7 ° C. Furthermore, it can be noted that the product has a maximum adsorption capacity of the order of 40 mg of As / gram of solid.
- EXAMPLE 2 This test is carried out on natural water from the Rennes region, which has been clarified by a coagulation / flocculation treatment, and which we then doped with arsenic (V) at a level of 100 ⁇ g of As (V) / liter using an AS 2 O 5 arsenic oxide solution.
- the dosage of natural organic materials is carried out by u.v. spectrophotometry. at 254 nm with a Shimadzu UV-160 model 204-04550.
