Abstract

The invention discloses a cationic resin regenerant and a method for regenerating cationic resin with the cationic resin regenerant. The regenerant comprises, by weight, 60%-80% of sodium citrate, 10%-20% of sodium gluconate, 5%-15% of sodium hexametaphosphate and 1%-10% of sodium hydroxide. The regenerating method includes the steps that 1, washing is carried out with purified water; 2, first regeneration is carried out through the regenerant; 3, second regeneration is carried out through the regenerant; 4, cleaning is carried out with purified water. By means of the regenerant and the regenerating method, the regenerating cationic resin can be directly regenerated in a stainless steel resin softening tank, the regenerating efficiency of the resin is improved, and the regenerating cost of the resin is reduced; the quality safety of the product is greatly improved; the cationic resin regenerant is mainly used for products such as water, fruit juice, herbal tea, traditional-Chinese-medicine extracting liquid and prepared wine with the softening requirement, the calcium ion content of the product is decreased, and the stability of the product is improved.

Description

technical field [0001] The present invention relates to a cationic resin regenerant and a method for regenerating cationic resin, in particular to a new regeneration method for strongly acidic styrene-based cation exchange resin, which is mainly used in water, fruit juice, herbal tea, traditional Chinese medicine extract, prepared wine, etc. The product needs to be softened to reduce the calcium ion content of the product and improve the stability of the product. Background technique [0002] Due to the addition of various animal and plant substances, products such as fruit juice, herbal tea, Chinese medicine extract, and formulated wine have complex functional components, and product precipitation problems such as precipitation and loss of light often occur, affecting product quality and becoming an industry problem that plagues product competitiveness. After analyzing the physical and chemical indicators of the collection and precipitation of the above products, it was fou...
