Application of Modified Nanoclay Sorbent for Separation and Preconcentration Trace Amount of Cobalt
The present article reports on the application of modified organo nanoclay as a green, easily prepared and stable solid sorbent for the preconcentration of trace cobalt ion in aqueous solution. The organo nanoclay was modified by adsorption of 5-(4-dimethyl amino-benzylidene) rhodanin reagent onto it. The sorption of Co2+ ions was quantitative in the pH range of 7.0 to 8.5, whereas quantitative...

متن کاملSelective Separation and Preconcentration of trace Amounts of Gallium in Water and Rice Samples using Cloud Point Extraction and Determination by Inductively Coupled Plasma-Atomic Emission Spectrometry
In the present study a cloud-point extraction process using non-ionic surfactant Triton X-114 for selective extraction of gallium from aqueous solutions was developed. The method is based on the complex formation of Ga (III) with N, N′ -bis (salycilidene)-1, 2-phenylenediamine (salophen) as a chelating agent in buffer media of pH 5. After phase separation and dilution of the surfactant-rich pha...
متن کاملCationic polyelectrolyte copolymer modified polyurethane foam for flow injection preconcentration and separation of trace amounts of β-lactam antibiotics.
A more sensitive flow injection preconcentration method has been developed for the determination of four β-lactam antibiotics (BLAs) namely cefaclor, cefotaxime, amoxicillin and ampicillin in urine, pharmaceuticals and milk. A mini-column packed with PUF functionalized with the cationic polyelectrolyte, poly(N-chloranil N,N,N',N'-tetramethylethylene diammonium dichloride) PCTDD, was utilized fo...
متن کاملSolid-phase Extraction Using Modified Carbon Nanotube and Cupferron Ligand for Preconcentration and Determination of Trace Amounts of Copper in Real Samples
A solid phase extraction procedure for simultaneous separation and preconcentration of traceamounts of Cu+2 ion from various real samples prior to its determination by flame atomicabsorption spectrometry has been developed. The proposed method is based on the utilization ofmultiwalled carbon nanotube in combination with Cupferron ligand as a solid phaseextractant. The influences of the analytic...
