Preparation and application of Ni(ii) ion-imprinted silica gel polymer for selective separation of Ni(ii) from aqueous solution
In the present study, a novel Ni(II) ion-imprinted sulfonate functionalized silica gel polymer was prepared with the surface imprinting technique by using nickel(II) as the template ion, grafted silica gel as the support, and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and ethylene glycol dimethacrylate (EGDMA) as the functional monomer and crosslinker, respectively. The sorbent was cha...
متن کاملAdsorption of Lead from Aqueous Solution by Modified Beech Sawdust
Sawdust is now being investigated as an adsorbent to remove contaminants from aqueous solution. Heavy metals can be decreased very effectively with the organic material. In this research, adsorption of Pb (II) onto modified beech sawdust in a batch system was investigated. Sawdust was collected from timber mill of Qom, Iran, and modified with H2SO4 and NaOH. Then, the effe...
متن کاملAdsorption of chloroform from aqueous solution by nano -TiO2
In this study, nano-TiO2 was employed for the adsorption of chloroform from aqueous solution in batch equilibrium experiments to investigate its adsorption properties. The effects of pH, initial chloroform concentration and nano-TiO2 dosage were also investigated. Optimal conditions for chloroform removal by nano-TiO2 have been then identified. Results of equilibrium experiments showed that the...

متن کاملSynthesis and Evaluation of Molecularly Imprinted Silica Gel for 2-Hydroxybenzoic Acid in Aqueous Solution
A molecularly imprinted silica gel sorbent for selective removal of 2-Hydroxybenzoic acid (2-HA) was prepared by a surface imprinting technique with a sol-gel process. The 2-HA molecularly imprinted silica gel (2-HA-MISG) sorbent was evaluated by various parameters, including the influence of pH, static, kinetic adsorption and selectivity experiments. The optimum adsorption capacity to the 2-HA...
