Abstract: | The authors present basic science for, elaborate and set as methodic recommendations some potentiometric methods using ion-selective electrodes. Efficiency of those methods was proved in experiments with such substances as boron compounds, hydrogen cyanide, hydrogen chloride. High sensitivity, selectivity, accuracy and rapidity of the methods with handy technique make the facilities available for analysis of air at workplace, ambient atmosphere, water and biologic materials, detecting wide range of concentrations. Practical application of the methods enabled to specify measures to preserve health of workers and general population, helped in hygienic evaluation of work conditions in composition materials production, high-temperature soldering, optic glass industry. |
