| description | The relevance of the work: The research on development of new methods for analysis which allow increasing significantly the sensitivity of instrumental methods is relevant; it extends the analytical possibilities of the latter. Classical spectral methods of atomic-emission and absorbing spectrometry do not provide the level of maximum permissible concentration for all elements at environmental monitoring. Application of polymer microfiber sorbents with primary sorption capacity which can be strengthened by developing various surface compositions and modification is promising for concentration of trace contaminant. The efficiency of extracting metal ions when using polymer microfibres can also be strengthened significantly by adding coagulants into solution. The aim of the work: the increase of efficiency of extracting metal ions from water environments with the effective coagulant on a flocculating microfibrous sorbent. Methods of the research: The authors have applied the method of atomic-emission spectrometry with multichannel analyzer emission spectra which allows analyzing at the level of maximum concentration limit of a wide range of defined metals. For this method the technique of sample preparation was improved. It consists in elimination of matrix influence of the coagulants entered. To assess the correctness and the reliability of the results received the authors applied the nuclear and absorbing spectrometry method. Results: introduction of an effective coagulant succeeded to improve considerably sorption of iron, copper, zinc, nickel, cadmium ions from water environments on a flocculating polymeric microfibrous sorbent. The authors improved the preparation of tests of toxic metal impurity concentrates based on polymeric sorbents to the analysis by a method of atomic-emission spectrometry with multichannel analyzer emission spectra. The paper introduces the method to eliminate the coagulant matrix influences when carrying out the spectral analysis, by introduction of special carriers. Based on the improved method for sample preparation and metrological estimation of spectral analysis of a concentrate the authors developed the method of atomic-emission analysis of waters with preliminary sorption concentration of impurities (K=5000). The method allows determining the content of copper, zinc, nickel, cadmium at maximum permissible concentration level and lower with a relative standard deviation of not more than 25 %. |
