【摘要】 研究了亚硫酸钠的除氧效果,讨论了pH值、钙镁离子浓度、有机催化剂对苯二酚对亚硫酸钠除氧效果的影响。实验表明:常温,无催化剂时,单独使用亚硫酸钠除氧,最大除氧率为95.8%。有机催化剂对苯二酚的加入明显地降低亚硫酸钠用量,提高了除氧率,在600mL水样中,当亚硫酸钠加入量51mg,对苯二酚加入量为4mg,除氧率为98.9%。更多还原

【Abstract】 The effect of pH value?concentration of Ca2+?Mg2+,organic catalyst hydroquinone on the deoxidize rate of Na2SO3 was studied respectively.The experimental results show that the deoxidize rate of Na2SO3 only reached 95.8% without catalyst. The deoxidize rate of Na2SO3 was raised distinctly when organic catalyst has been introduced.The deoxidize rate higher than 98.9% ,when dosage of Na2SO3 was 51 mg,added amount of hydroquinone was 4 mg.更多还原
