Bismuth has been on sale since ancient times but was sometimes confused with lead, until 1753 when it was distinguished from lead. The origin of the word bismuth is not clear. It may be derived from the Arabic word "biasemutum" (similar to kohlrabi) or the German words Weisse Masse and Wismuth meaning white mass, which became the Latin, word Bisemutum in the 16th century. Isolation and measurement of small amounts of bismuth are of particular importance in two ways, including environmental hazards and industrial applications. This study investigates the synthetic parameters of the process of adsorption of bismuth by coconut skin. In the first step, the order of the bismuth adsorption synthetic reaction was obtained based on nonlinear regression analysis, and then the reaction constant-coefficient was calculated using a combination of MATLAB and GA Simulink environment. The results and calculations showed that the relevant reaction which is quadratic and the constant coefficient of bismuth adsorption reaction is equal to 0.0076 L\mg.h.
