Abstract
The invention provides an environment-friendly reverse osmosis (RO) scale inhibitor and a preparation method thereof. The RO scale inhibitor comprises the following components by weight percent: 5-20% of 4-hydroxyamphetamine, 10-30% of polyamino polyether methylene phosphonate, 20-50% of hydroxyethylidene diphosphonic acid and the balance of deionized water. The RO membrane scale inhibitor product is prepared by adding the components to a reaction kettle in sequence and starting a stirring motor. When the scale inhibitor is used in an RO system for water treatment, the problem of deposition of dirt on an RO membrane, such as calcium carbonate, calcium sulfate, magnesium carbonate, calcium phosphate, barium sulfate, ferric oxide and colloidal silica, can be solved, thus improving the work efficiency of the RO system, prolonging the service lives of the RO membrane and RO equipment and reducing the RO cost.
