Abstract:
     This invention is a preparation used for whitening sodium sulfate and belongs to the technical field of sulfate production. It is a combined material for whitening processing in which fluorescent brightener is used as main agent, phenolic-ether and alcoholic-ether non-ion surfactants as synergist, and alcohol kind and deionized water as solvent. The weight percentages of each components are as follows: fluorescent brightener (1-5%), alcoholic-ether surfactant (2-5%), phenolic-ether surfactant (8-15%), alcohol kind (1-5%), and deionized water (70-88%). If this agent is used to process sodium sulfate, its whitenness value can be relatively increased by 5 degrees.
