Claims
- 1. A composition for water treatment comprising:a) biodegradable organic polymers having repeating succinyl units, b) a biocidal oxidizing agent, and c) an unsubstituted or substituted amidosulphonic acid, wherein the unsubstituted or substituted amidosulphonic acid is present in a concentration sufficient to prevent or substantially reduce the reaction between a) and b).
- 2. The composition of claim 1, wherein the amidosulphonic acid comprises H2NSO3H.
- 3. The composition according to claim 1, wherein the biodegradable organic polymers have repeating succinyl units of the structures selected from the group consisting of:
- 4. The composition according to claim 1, wherein the biocidal oxidizing agent is hydrogen peroxide, chlorine, bromine, chlorine dioxide, hypochlorite, hypobromite or ozone; or a reaction product of: (i) a component selected from the group consisting of hydrogen peroxide, chlorine, bromine, chlorine dioxide, hypochlorite, hypobromite, and ozone; and (ii) water.
- 5. A composition for water treatment comprising:a) biodegradable organic polymers having repeating succinyl units b) a biocidal oxidizing agent, and c) an unsubstituted or substituted amidosulphonic acid, wherein the biodegradable organic polymers contain repeating units selected from the group consisting of the formulae: wherein the unsubstituted or substituted amidosulphonic acid is present in a concentration sufficient to prevent substantially reduce the reaction between a) and b).
