Working Process

Chemical equation: 2NaOH+H2S=NA2S+2H2O
NA2S+H2S=2NAHS
First Step: Use sodium hydroxide liquid absorb hydrogen sulfide generate sodium sulphide
Second Step: When sodium sulfide absorption saturation,continue to absorb hydrogen sulfide generate sodium hydrosulphide.

Sodium hydrosulfide have 2 kinds of appearance,70%min yellow flake and 30% yellowsih liquid.
We have different specs which depends on Fe content,we have 10ppm,15ppm,20ppm and 30ppm.Different Fe content,the quality is different.
