Influence of the synthesis conditions on the characteristics and metal adsorption properties of the 3-(1,4-phenylenediamine)propylsilica xerogel
The hybrid 3-(1,4-phenylenediamine)propylsilica xerogel was obtained starting from two different organic precursor quantity (5 and 8 mmol) to 22 mmol of TEOS, in the synthesis. The xerogel samples were characterized by using CHN elemental analysis, N 2 adsorption-desorption isotherms, infrared therm...

| Summary: | The hybrid 3-(1,4-phenylenediamine)propylsilica xerogel was obtained starting from two different
organic precursor quantity (5 and 8 mmol) to 22 mmol of TEOS, in the synthesis. The xerogel samples were
characterized by using CHN elemental analysis, N 2 adsorption-desorption isotherms, infrared thermal
analysis. The xerogel was used as metal sorbent for Cu 2+ , Cd 2+ and Pb 2+ in aqueous solution with
concentration range of 10 -3 to 10 -5 mmol l -1 . The quantity of organic precursor added in the synthesis
influences the characteristics of the xerogel as morphology and thermal stability, as well as the metal
adsorption capacity. |
