This experimental study aimed to compare the adsorption of B₁₂ by twoadsorbent; SWCNTs and MWCNTs by use of Uv-Vis spectrophotometer Jenway 6505model. In this study, four different concentrations of B₁₂ in the range of 212.nm were used. In all conducted experiments, the values of adsorbents, exposure time, temperature, andpH were assumed constant. Based on the results, under similar conditions the efficiency of adsorptionof B₁₂ by MWCNTs was more than SWCNTs. The results can be beneficial inpharmaceutical, oil and construction industries, biology and advanced water and wastewater treatmentplant.
