被引用回数：158 パーセンタイル：99.25(Chemistry, Analytical)In this study, we have developed S and N containing ligand of 5-tert-butyl-2-hydroxybenzaldehyde thiosemicarbazone. The organic ligand was anchored onto the mesoporous silica by an indirect method for the preparation of composite adsorbent. The adsorbent can detect Pd(II) ions at ultra-trace levels and recover the Pd(II) with high sorption capacity and efficiency. The adsorption isotherm data were well fitted with the Langmuir model, and the maximum sorption capacity of the composite adsorbent was 171.65 mg/g, which was close to the equilibrium sorption capacity.

被引用回数：259 パーセンタイル：99.35(Engineering, Environmental)The functional group containing organic ligand was developed and then successfully anchored onto mesoperous silica for the preparation of nano-conjugate adsorbent. After fabrication, the ligand kept open functionality for capturing Pd(II) under optimum conditions. The adsorbent exhibited the distinct color formation after adding the Pd(II) ions both in solid and liquid states. The base metal of Cu(II) and Zn(II) did not hamper the Pd(II) sorption ability of adsorbent in the acidic pH region. Therefore, it was expected that the Pd(II) could be separated from other hard metal ions by the adsorbent. Therefore the proposed adsorbent can be considered as a potential candidate for Pd(II) capturing from waste samples.
