Abstract
PURPOSE: To enable measurement to be made over a long period of time without deterioration of a Cd electrode even when ions such as Cu2+, Fe3, etc. and organic materials coexist by using the specific masking agent, active carbon column and anion exchange resin column.
CONSTITUTION: A reagent 3 for dissolution is dosed into the sample which has been drawn at a fixed volume into a heating dissolution bath 5 from a sample drawing part 1 and solids are dissolved through heating treatment by an electric heater 6. The solution is sucked from the bath 5 by a pump 11 and insoluble materials are separated by a filter 7. The masking agent 9 composed of salycilic acid and thiourea is proportionally dosed into the filtrate, then Cu2+, Fe3, etc. become complex. Next, organic materials are adsorbed on the active carbon column 10 and Cd2+ on the anion exchange resin column 16. As solenoid valves 12, 13 are changed over, the eluate 14 is sent to the column 16 and a buffer 18 is added to a fixed volume of the eluate 17. The solution 17 having been controlled to a constnat pH is sent to measuring part 21, and the Cd2+ concentration measured with an ion densitometer 22 is recorded in a recorder 23.
