摘要
研究在中性条件下 Mn(Ⅱ)液相催化氧化低浓度 SO_2,生成铵肥的可能性,研究表明当 pH=4～5时在饱和(NH_4)_2SO_4浓度范围内均可获得95%以上的吸收效率.
A process of catalytic oxidation of SO_2in water solution of(NH_4)_2SO_4 containing Mn(Ⅱ) as a catalyst to produce ammonium sulfate has been studied.The results of experiments show that the absorption efficiency of SO_2 η≥95% as pH=4～5.
