    摘要: A complex comprising a charged species, a polymer comprising ionisable groups, and an ionic surfactant, wherein the charged species is a positively charged species and the ionic surfactant is an anionic surfactant, or the charged species is a negatively charged species and the ionic surfactant is a cationic surfactant. The charged species may comprise a metal such as cadmium, chromium, copper, magnesium, nickel, arsenic, lead, mercury, selenium, silver or zinc. The anionic surfactant may comprise an anionic functional group selected from sulphate, sulphonate, phosphate, phosphonate and carboxylate. The cationic surfactant may comprise a cationic functional group selected from a quaternary ammonium or a cationic nitrogen containing group. The polymer comprising ionisable groups may be selected from the group of polyethyleneimine (PEI), polydiallyldimethylammonium chloride (PolyDADMAC) or polystyrene sulphonate (PSS). A process comprising treating a solution with an ionic surfactant and a polymer comprising ionisable groups, wherein the solution comprises a charged species, to form a complex as claimed is also provided. Application of such treatment to the removal of heavy metal ions from aqueous effluents is also provided; such removal can be achieved via filtration of the complex from the effluent.

    摘要: A method of optimising the filter action of a filtering means in an aqueous containing liquid system in which the aqueous containing liquid system passes through an in-line mechanical filter means is characterised by introducing an additive formulation comprising a soluble polyelectrolyte dispersant into the aqueous containing liquid system. Unlike a conventional cleaner, the additive formulation is not flushed from the system by draining the circuit and then replacing the system water, but remains in the system to effect removal by an in-line filter of the particulate debris upon which it has acted. Further, in remaining in the system, the additive formulation will disperse and suspend any solid particulate matter subsequently formed (e.g. by corrosion) or introduced into the system to allow effective capture by the filter.
