Headspace Microextraction of Tin into an Aqueous Microdrop Containing Pd(II) and Tributyl Phosphate for its Determination by ETAAS
O estudo introduz um método para microextração por headspace (HS-SME) de hidreto de estanho em uma microgota aquosa contendo Pd(II) e tributil fosfato (TBP) como uma estratégia de enriquecimento e de modificação de matriz previamente à determinação por ETAAS. O hidreto de estanho foi gerado pela adição de um volume fixo de solução de borohidreto de sódio na amostra. Os efeitos de vários parâmet...

this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...
Optimization of the headspace solid-phase microextraction for determination of glycol ethers by orthogonal array designs.
A headspace solid-phase microextraction (HS-SPME), in conjunction with gas chromatography-flame ionization detection for use in the determination of six frequently used glycol ethers at the microg/l level is described. A 75 microm Carboxenpolydimethylsiloxane fiber was used to extract the analytes from an aqueous solution. Experimental HS-SPME parameters such as extraction temperature, extracti...
متن کاملTransport of Metal Ions through Cellulose Fiber Supported Solid Membrane into Tributyl Phosphate Containing Mixed Solvents
A novel cation exchange fiber supported solid membrane was developed for transport of cobalt, manganese and nickel metal ions. Fiber supported solid membrane was prepared by chemically modifying the cellulose fibers with citric acid. In the fiber supported solid membrane, the diffusion by capillary action by keeping the liquid phase in the porous solid fiber and ion exchange mechanism were used...
متن کاملHeadspace Liquid Microextraction
2 Headspace sampling for gas chromatographic (GC) analysis has many advantages, the most important of which is the elimination of many interferences from the sample matrix. In addition to the standard methods for headspace sampling, the technique of solid-phase microextraction (SPME) has found wide acceptance because it is simple and inexpensive. More recently, single-drop microextraction (SDME...
