Hollow Fiber Supported Liquid Membrane Extraction Combined with HPLC-UV for Simultaneous Preconcentration and Determination of Urinary Hippuric Acid and Mandelic Acid
This work describes a new extraction method with hollow-fiber liquid-phase microextraction based on facilitated pH gradient transport for analyzing hippuric acid and mandelic acid in aqueous samples. The factors affecting the metabolites extraction were optimized as follows: the volume of sample solution was 10 mL with pH 2 containing 0.5 mol·L-1 sodium chloride, liquid membrane containing 1-oc...
متن کاملEnantioseparation of Racemic α-Cyclohexyl-Mandelic Acid across Hollow Fiber Supported Liquid Membrane
Este artigo trata da separação enantiomérica do ácido α-cicloexilmandélico contendo cobre(II) N-dodecil-(L)-hidroxiprolina (CuN 2 ) como um carregador quiral, usando uma membrana líquida suportada em fibra oca. Um modelo matemático de transporte e separação enantiomérica de compostos quirais foi deduzido; o coeficiente de partição observado entre a fase de alimentação e a membrana, a fase de el...
متن کاملRacemic -cyclohexyl-mandelic Acid Resolution across Hollow Fiber Supported Liquid Membrane
This paper deals with the resolution of racemic -cyclohexyl-mandelic acid containing copper(II) N-dodecyl-(L)-hydroxyproline (CuN2) as a chiral carrier across hollow fiber supported liquid membrane. A mathematical model of transport and resolution of chiral compounds was deduced, the observed partition coefficient between the feed phase and the membrane phase, the stripping phase and the membra...
متن کاملD2EHPA-Sulfuric Acid System for Simultaneous Extraction and Recovery of Nickel Ions via Supported Liquid Membrane Process
This research addresses the extraction and recovery of nickel ions from real electroplating wastewater using SLM process. The process involves three main phase system which are feed, organic and stripping phase. The feed phase containing the nickel electroplating wastewater whereas the organic phase containing the liquid membrane which was immobilized in the membrane support. The liquid membran...
