Solid phase extraction of zinc with octadecyl silica membrane disks modified by N,N’-disalicylidene-1,2-phenylendiamine and determination by flame atomic absorption spectrometry
A procedure for separation and preconcentration of trace amounts of Zn(II) from aqueous media is proposed. The procedure is based on the adsorption of Zn2+ on octadecyl bonded silica membrane disk modified with N,N’-disalicylidene-1,2-phenylendiamine at pH 7. The retained zinc ions were then stripped from the disk with a minimal amount of 1.5 mol L-1 hydrochloric acid solution as eluent, and de...
متن کاملCold Vapor Atomic Absorption Determination of Hg in Crude Oil and Gasoline Samples after Solid Phase Extraction Using Modified Disks
A facile and highly efficient method have been developed for the preconcentration of the mercury content in crude oil and gasoline samples after digestion with microwave-assisted digestion. Octadecyl silica membrane disk has been modified by the recently synthesized triazene ligand, (E)-1-(2-ethoxyphenyl)-3-(4-nitrophenyl) triaz-1-ene (ENT), then the modified membrane was used for the preco...
متن کاملsolid phase extraction of trace copper in aqueous samples using c18 membrane disks modified by benzildithiosemicarbazone prior to flame atomic absorption spectrometric (faas) determination
a highly convenient, selective and sensitive procedure for pre-concentration, separation and determination of sub-ppm levels of cu 2+ in aqueous samples based on modification of octadecyl silica bonded phase membrane (osbpm) disks is described using benzildithiosemicarbazone (bdsc) as a powerful modifier. it was revealed that each loaded osbpm disk with 6.0 mg of bdsc serves as excellent bead ...
متن کاملDetermination of Cadmium by Flame-Atomic Absorption Spectrometry After Preconcentration on Silica Gel Modified with Cupferron
Este trabalho descreve um método para a pré-concentração de cádmio com sílica gel modificada com cupferron e sua determinação por espectrometria de absorção atômica com chama. O efeito do pH, a quantidade do material adsorvente, a concentração de eluente, volume da amostra e quantidade do analito adsorvido foram otimizados. O efeito de interferentes foi avaliado para diversos íons mostrando que...
متن کاملDetermination of lead and cadmium in water samples by cloud point extraction prior to flame atomic absorption spectrometry determination
Pb and Cd in water samples were determined by cloud point extraction (CPE) with sodiumdiethyldithiocarbamate (DDTC) as the chelating agent and octylphenoxypolyethanl (Triton X-114) asthe surfactant prior to flame atomic absorption spectrometry (FAAS) determination. The main factorsof affecting the extraction and detection processes were optimized. The preconcentration of 10 mL ofstandard soluti...
