MultiSimplex optimization of on-line sorbent proconcentration and determination of iron by FI-AAS and microcolumn of immobilized ferron

Synthesis of a novel chelating resin and its use for selective separation and preconcentration of some trace metals in water samples

“…Manganese is a necessity for the proper function of several enzymes and an essential micro-nutrient for the function of the brain, nervous system and normal bone growth. It optimizes enzyme and membrane transport functions [6][7][8].…”

Applications of Amberlite XAD based Chelating resins in Online Pre concentration of metal ions

“…The chelating resins can be used in flow injection system with various detection methods like FAAS, ICP-AES, spectrophotometry, chemiluminescence and ICP-MS etc [26].There are various chelating resins have recently been used such as polyurethane foam [27][28][29][30][31][32][33][34][35], cellulose, silica gel [36][37][38][39][40][41][42], alumina [43][44][45][46][47][48], chitosan [49][50][51], carbon active [52] and polymeric resins like Amberlite etc. Amberlite XAD resins widely used to develop several chelating materials for preconcentration procedures due to its good physical and chemical properties such as porosity, high surface area, durability and purity.…”

Modified Bentonite with Dithizone as Nano Clay Mineral Adsorbent for Solid Phase Extraction of Silver Ions

“…The hollow cathode lamp current was 4.0 mA, the wavelength was set at 328.1 nm (the resonance line of silver) and the slit width was 1.2 nm. The flow injection system used were as previously described, [6,17] and consisted of a peristaltic pump (Ismatic, MS-REGLO/8-100, Switzerland), a rotary injection valve (Rheodyne, CA, USA), and a microcolumn (PTFE tube 3 cm × 4 mm id) of dithizone immobilized on surfactant-coated Bt. The schematic diagram of flow injection system used is provided in Figure 1.…”
