As the electrochemical method, the Fast Fourier Transform (FFT) Stripping Cyclic Voltammetry detection method was designed for measurement and monitoring of adsorbed mercury ions by new modified adsorbent based on mesoporous silica as a new adsorbent. In this respect, SBA-15 as mesoporous silica and 1, 3, 5 Trithiane as effective modifier ligand were chosen, and the modification process was carried out physically. Continuing research application of modified mesoporous silica for the removal of mercury ions (Hg2+) from the aquatic environment in different pH, the weight of adsorbent and, stirring time as the major parameters were investigated and analysis of flow-injection was used as the major method for determination of adsorbed mercury ions by modified SBA-15. Also, a special computer numerical technique is used to calculate Hg response based on the total charge exchange at the electrode surface, where the currents were integrated into the range of reduction of Hg. The time for stripping was less than 300 ms. The results showed that the best Hg2+ ions removal conditions were achieved at the 15.0 mg of modified adsorbent, pH 5.0 and stirring time 15 min; Also the maximum percentage removal of Hg2+ ions and the capacity of the adsorbent were found to be 85% and 10.6 mg of Hg2+ ions /g modified SBA-15, respectively.
