The Study of Acidic Decomposition Zinc Sulfite

亚 硫酸 锌酸分解研究

The required zinc sulfite may be prepared by using zinc calcine or flue dust to absorb the acid waste gases ( containing 0.2-0.5 % SO_2 ) thus simultaneous solving the waste gas pollution problem ;

亚 硫酸 锌可由制酸尾气（含SO20.2～0.5%）用焙砂或烟尘吸收获得，同时顺便解决了废气污染问题；

The Study on Reaction of Zinc Sulfite by Blasting Air

亚 硫酸 锌空气氧化的研究

Zinc sulfite is an active reducing agent capable of performing reduction at low temperature in a short time with small excess of reagent and high reductive rate .

亚 硫酸 锌是一种活性还原剂，还原过程温度低、时间短、过剩系数小、还原率高。

The reconstitution green method that Zinc salt and sodium sulfite are used to soak the wild celery to resume its natural green colour and add sodium sulfite to adjust the PH is adopted the blanching technique is employed to kill microorganism and prevent its browning .

采用 锌盐和 亚硫酸钠浸泡复绿法使其恢复天然绿色；采用加亚硫酸钠、调PH等方法，并使用漂烫技术，既可杀死微生物，又可以防止褐变；
