Wherein casing 1 for splendid attire detect reagent 3,3 ', 5,5 '-tetramethyl benzidine, is made by brown glass, there is thread sealed closure 5 upper end; Casing 2, for splendid attire water sample to be measured, is made by clear glass, and surface is with 50mL scale mark, and there is thread sealed closure 6 upper end; Casing 3 for splendid attire single detect with detect reagent 3,3 ', 5,5 '-tetramethyl benzidine, is made by clear glass, and volume is fixed as 2.5mL, casing 3 is positioned under casing 4, casing 1, casing 3 and casing 4 combinations, casing 2 threes are connected arrangement, have a valve A between casing 3 and casing 1, and valve A is by switch a gauge tap, between casing 3 and casing 2, there is a valve B, valve B is by switch b gauge tap, and switch a and switch b are by lock formula switch, and switch knob stretches out outside kit; Casing 3 is controlled and is connected with casing 1 and casing 2 by switch a and switch b respectively; The positive upper end of casing 3 has a vent port 12 to maintain casing 3 inside and outside air pressure balances, guarantees that liquid flows to smoothly and flows out, and vent port 12 connects a tubule outward upward at box and do not make overflow; Casing 4 is blank when detecting for splendid attire water sample to be measured, by clear glass, is made, and chlorine residue standard color comparison card 14, with a draw-in groove, can be inserted in its front, and there is thread sealed closure 7 casing 4 upper ends; Casing 2, casing 4 back sides are all covered with white film, color contrast during for increasing detection, in the middle of shadow shield 15, there is a rectangle perforate, when casing 2 and casing 4 carry out colorimetric, only rectangle perforate is aimed to the corresponding vitta position of chlorine residue standard color comparison card 14.
Detection method when carrying out chlorine residue detection, step is:
(1) press switch a and open valve A, make detection reagent 3,3 in casing 1 ', 5,5 '-tetramethyl benzidine enters casing 3 by valve A, treat 3,3 ', 5,5 '-tetramethyl benzidine is full of after whole casing 3, thereby decontrols switch a valve-off A;
(2) press switch b and open valve B, whole device is tilted to the right simultaneously make 3,3 in casing 3 ', 5,5 '-tetramethyl benzidine reagent all flows into after casing 2 by valve B, thereby decontrols switch b valve-off B;
(3) with 47.5mL measuring cup, accurately measure water sample to be measured and pour casing 2 into, with water sample to be measured, fill casing 4 simultaneously, respectively threaded together gland bonnet 6, thread sealed closure 7;
(4) water sample to be measured and 3 in confirming casing 2,3 ', 5,5 ' after-tetramethyl benzidine cumulative volume is 50mL, rock gently device make water sample to be measured and 3,3 ', 5, colorimetric immediately after 5 '-tetramethyl benzidine mixes, can select single color compare respectively with shadow shield 15 during colorimetric, and acquired results is free chlorine residual; Place 10min, colorimetric acquired results is total residual chlorine; Total residual chlorine deducts free chlorine residual and is chemical combination chlorine residue;
(5) detect completely, use water sample to be measured that casing 2 is swung and washed.
The beneficial effects of the utility model: this chlorine residue quick detection kit has the features such as easy and simple to handle, with low cost, simple in structure, stability is strong.Owing to having used liquid detecting reagent to mix with water sample to be measured rapidly, can guarantee the accuracy of testing result.Mass concentration that can chlorine detection is from the water sample of 0.005～10mg/L, and wide coverage is widely used in the Site Detection of the residual chlorine concentrations such as Drinking Water, swimming-pool water, life and hospital sewage.
