Synthesis of a novel chelating resin for the separation and preconcentration of uranium(VI) and its spectrophotometric determination.
A novel chelating polymer including three different functional groups, such as amidoxime (-C(NH(2))=NOH), azo (-N=N-) and carboxylic acid (-COOH), was synthesized. The poly(acrylamidoxime-co-(1-(2-pirydylazo)-2-naphtyl-2-methacrylate)-co-methacrylicacid) (APM) polymer, prepared in three steps, was characterized by FT-IR and elemental analyses. The resin was used for solid-phase extractive separ...
متن کاملDetermination of molybdate in environmental water by ion chromatography coupled with a preconcentration method employing a selective chelating resin.
A simple and sensitive suppressed ion chromatography (IC) method with conductivity detection for the determination of molybdate in environmental water is proposed. Molybdate in highly saline water was extracted and preconcentrated. Preconcentration was accomplished by using a chelating resin using a chelating resin immobilized with carboxymethylated polyethylenimine (Presep(®) PolyChelate). Thi...
متن کاملSpectrophotometric Determination of Scandium(III) in Monazite after Separation Using Amberlite IRC 718 Chelating Resin
The spectrophotometric determination method of scandium with eriochrome cyanine R (ECR) and the composition ratio of the complex were investigated in the presence of surfactants. A volume of 5 mL of 1.0×10−3 M ECR and 10 mL of 2.0×10−4 M CTMAB are necessary for the determination of 1.0×10−7 ~ 3.0×10−6 M Sc(III) at pH 6.5. The apparent molar absorption coefficient of the Sc(III)-ECR-CTMAB, terna...
متن کاملApplication of iminodiacetate chelating resin muromac A-1 in on-line preconcentration and inductively coupled plasma optical emission spectroscopy determination of trace elements in natural waters
On-line system incorporating a microcolumn of Muromac A-1 resin was used for the developing of method for preconcentration of trace elements followed by inductively coupled plasma (ICP) atomic emission spectrometry determination. A chelating type ion exchange resin has been characterized regarding the sorption and subsequent elution of 24 elements, aiming to their preconcentration from water sa...
متن کاملSpectrophotometric determination of trace amount of malachite green from water with novel magnetic silica nanoparticles
A nano-hybrid based on polystyrene derivatives and magnetite was introduced as a new sorbent for pretreatment and determine the trace amount of malachite green from aqueous solution by spectrophotometry after preconcentration by solid phase extraction (SPE). UV–Vis spectrophotometer was used for determination of MG concentration after desorption of the dye by hydrochloric acid solution in the s...
