2state is constant; Six-way valve V goes to the right position of Fig. 2 state, and interface 1 communicates with 6, and 2 communicate with 3, and 4 communicate with 5; Peristaltic pump P rotates again, quantitatively the water sample in ring Ls passes through the soft post C of low pressure enriched by enrichment under the promotion of eluent, subsequently by eluent wash-out, in elution process, the analyte eluting has a concentration gradient, the concentration of the contained analyte of eluant, eluent head is the highest, has therefore ensured the concentration effect of heavy metal ion.Afterwards, the eluent that is loaded with copper zinc chrome cadmium ion enters threeway mixer Y
1in mix with buffer B, mixed liquor enters bumper ring L subsequently
1in reach the effect of pH of regulating, afterwards, at threeway mixer Y
2in mix with nitrite ion R, and at reacting ring L
2in react and develop the color, finally in Photoelectric Detection module 11, carry out the detection of photovoltage, intelligent control module 12 records and preserves base value I, the photoelectric signal obtaining is peak light voltage.
(3) cleaning process
Solenoid valve V
1, V
2and the state of six-way valve V is constant, peristaltic pump P is rotated further, until photovoltage value is got back to base value I
0, show that the soft post of pipeline and enrichment rinses well, stop peristaltic pump P.
(4) computation process
According to above the data obtained I
0with I, calculate the absorbance of water sample according to langbobier law, with S
1, S
2demarcate the typical curve comparison of gained, calculate the measured value of Copper in Water Samples zinc chrome cadmium ion and this value is shown on touch-screen DP automatically for 2.
The concrete steps that native system is demarcated are as follows:
When system is carried out timing signal, if solenoid valve V
2in interface select 2 to communicate with 3, solenoid valve V
1in interface select 1 to communicate with 2, quantitatively encircling sample quantitative in Ls is standard solution S
1if, solenoid valve V
2in interface select 2 to communicate with 3, solenoid valve V
1in interface select 2 to communicate with 3, quantitatively encircling sample quantitative in Ls is standard solution S
2, all the other steps are the same with sample detection step.Finally, according to S
1with S
2absorbance drawing standard curve, demarcating steps finishes.
