Abstract
The present invention relates to a kind of methods for detecting chlorine dioxide content in Drinking Water, it includes titration for the first time, second of content for titrating and calculating chlorine dioxide in water sample.The step of first time titration is：1) the phosphate buffer 3mL that pH is 68 is added in iodine flask；2) water sample 100mL is added；3) iodate k particle 1g is added, is rocked；Add in the Starch Indicator solution 3mL that mass percent concentration is 0.3%；4) after 15 minutes, by the use of the hypo solution of a concentration of 0.005mol/L as titrant, using microburet until blue just disappears；Therefore, the present invention has the advantages that detection is accurate, easy to operate and applied widely.
Description
Technical field
The invention belongs to chlorine dioxide content detection technique fields, and in particular to titanium dioxide in a kind of detection Drinking Water
The method of chlorinity.
Background technology
External a large amount of experimental study shows that chlorine dioxide is safe and nontoxic disinfectant, nothing " three cause " effect (carcinogenic,
Teratogenesis, mutagenesis), while also can not generate having for " three-induced effect " with organic matter generation chlorination generation in disinfecting process
Machine chloride or other toxic class substances.But due to chlorine dioxide have extremely strong oxidability, should avoid at high concentrations (>
500ppm) use；When concentration is used to be less than 500ppm, the influence to human body can be ignored, and when below 100ppm will not be right
Human body generates any influence, including Physiology and biochemistry in terms of influence.To skin also without any sensitization；In fact, two
The routine of chlorine monoxid will be well below 500ppm, normally only in tens ppm or so using concentration；Therefore, chlorine dioxide is also by state
Safe and nontoxic green disinfectant is known as on border.
Invention content
The purpose of the invention is to overcome the deficiencies in the prior art, and it is accurate, easy to operate and suitable to provide a kind of detection
With the method for chlorine dioxide content in the wide detection Drinking Water of range.
The object of the present invention is achieved like this：A kind of method of chlorine dioxide content in detection Drinking Water, it is wrapped
Include titration for the first time, second of content for titrating and calculating chlorine dioxide in water sample.
The step of first time titration is：1) the phosphate buffer 3mL that PH is 6-8 is added in iodine flask；
2) water sample 100mL is added；
3) iodate k particle 1g is added, is rocked；Add in the Starch Indicator solution that mass percent concentration is 0.3%
3mL；
4) after 15 minutes, by the use of the hypo solution of a concentration of 0.005mol/L as titrant, using microtitration
For pipe until blue just disappears, the amount for recording the sodium thiosulfate of titration is A；
Described second is the step of titration：1) the phosphate buffer 4ml that PH is 8 is added in another iodine flask；
2) water sample 100mL is added, sampling amount is identical with the sampling amount of first time titration；
3) it then passes to nitrogen to blow 30 minutes, whole chlorine dioxide in water sample of going out；
4) iodate k particle 1g is added, is rocked；Add in the Starch Indicator solution that mass percent concentration is 0.3%
3mL；
5) after 15 minutes, by the use of the hypo solution of a concentration of 0.005mol/L as titrant, using microtitration
For pipe until blue just disappears, the amount for recording the sodium thiosulfate of titration is B；.
It is the step of the content of chlorine dioxide in the calculating water sample：It is obtained using the ÷ V of calculation formula (A-B) × C × 16863
Go out the content of chlorine dioxide.
Beneficial effects of the present invention：The present invention examines the content of chlorine dioxide in water using chemical analysis, can effectively exclude
The interference of other ions, this method are easy to operate, applied widely.
