Class sulfide.Sulfide is one of important parameter representing Water quality.Owing to being affected, to it by degree of water pollution is different
The difficulty carrying out Accurate Determining is relatively big, and sample pretreatment is the key link during measuring.The content of Sulfide in water and gas
As relevant with environmental factors.Hydrogen sulfide easily from water loss to air, produce stink and there is toxicity, human body cell group can be caused
Knit anoxia, jeopardize the life of people.
The hydrogen sulfide nitrogen that sulfide in water and phosphatase reaction produce is carried by the blowning installation of sulfide determination
Taking out, in addition to the factor impacts such as blow air temperature, time gentle speed, blowning installation also has a major impact itself." water is supervised with waste water
Cls analysis method (third edition) " the blowning installation response rate relatively low, it affects link pretreatment, colour developing etc., blowning installation
Middle nitrogen at underwater bubble compared with the shortcoming big, dispersion is low, the holdup time is short and in bottle, entrapped gas volume is bigger.Exist with
Lower deficiency: one is that this device is the most numerous and diverse, and is hard glass, picks and places sample inconvenient, it is easy to damage；Two is that device is curved
Pipe, interface are more, clean more difficult；Three is after sample is blown, and color solution is during absorption chromoscope is transferred to color comparison tube
Easily cause escaping of sample, make analysis result on the low side.To this end, this pretreatment unit is improved." water divides with effluent monitoring
Analysis method (fourth edition) " blowning installation can only measure a water sample every time, and the response rate is relatively low, and nitrogen is at underwater bubble relatively
Greatly, dispersion is low, the holdup time is short, and the shortcoming such as in bottle entrapped gas volume is bigger, designs a kind of novel blowning installation, can
Measuring 2 samples, convenient and swift, automatization level improves, and the response rate is also greatly improved simultaneously.
