Abstract: The effect of surfactant concentration (Triton X-100) on increasing the sensitivity of the atomic absorption determination of Cadmium and Nickel was studied. It is shown that after the usage of Triton X-100 (? = 3%) sonication for 20 minutes, the sensitivity of the atomic absorption determination of Cadmium increases by 1.4 times, and Nickel does by 1.7 times. For complete extraction of analytes, ultrasonic treatment of soil samples with a power of 120 W, with a frequency of 40 kHz, was taken. The content of Cadmium and Nickel was determined by atomic absorption, atomic emission with inductively coupled plasma, and X-ray fluorescence methods in a soil sample using Cadmium and Nickel acetylacetonates as standard samples of the composition. The correctness of the results of the analysis was checked by the "injected-found" method. By varying the sample weight, the absence of substantial systematic error was confirmed. According to the Fisher criteria and Student's t-test, the consistency of the results obtained by two independent methods was evaluated. It is shown that the discrepancy of the means is not significant and is justified by a random scatter. The detection limits of Cadmium (Cmin=0,001 mkg/ml, Clit=0,007 mkg/ml ) and Nickel (Cmin=0,01 mkg/ml, Clit=0,02 mkg/ml ).were estimated by the atomic absorption method
