  Author(s): Benyamin Chahkandi, Mohammad Gheibi* and Amir Takhtravan
  
  Due to the wide application of bismuth in various industries and the environmental effects of its release in water and soil resources, the necessity of measuring its small amounts becomes apparent. Various decomposition methods such as electrochemical systems, molecular spectrophotometry, atomic absorption spectroscopy and ICP can be used to measure bismuth. In this study, 18 analytical measurement methods were evaluated in terms of economic, environmental, feasibility, measurement speed and accuracy. In this study, the Technique for Older-Preference by Similarity to Ideal Solution (TOPSIS) decision-making method was employed to analyze and prioritize different options. The results showed the implementation of molecular spectrophotometric systems such as color change, methylene blue-bismuth and ionic complex of iodide-bismuth absorption and atomic absorption spectroscop..
