Solid-phase extraction, separation, and visible spectrophotometric determination of trace amounts of iron in water samples.
A simple and reliable method is presented for the rapid extraction, separation, preconcentration, and determination of iron as its bathophenanthroline complex by the use of octadecylsilica membrane disks and spectrophotometry. We evaluted extraction efficiency, the influence of sample matrix, type and optimum amount of extractant, flow rates of sample solution and eluent, pH, amounts of bathoph...
متن کاملField determination of trace iron in fresh water samples by visual and spectrophotometric methods.
Sensitive visual and micro spectrophotometric methods have been developed for field determination of trace iron in fresh water samples. For the visual method, a water sample (0.45-microm filtrate acidified to 0.1 M HCl) was placed in a glass vial and mixed with a reagent solution containing 1,10-phenanthroline, sodium thiocyanate and 0.1 M HCl. Iron was extracted as pink ferroin thiocyanate wit...
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...
متن کاملSequential determination of trace amounts of iron and copper in water samples by flow injection analysis with catalytic spectrophotometric detection.
A simple flow injection analysis (FIA) method is described for the sequential determination of iron and copper. The detection method for iron and copper is based on their catalytic activities in the oxidation reaction of N,N-dimethyl-p-phenylenediamine (DPD) with hydrogen peroxide. The sequential determination of iron and copper can be carried out by injecting two sample plugs into the FIA syst...
متن کاملSpectrophotometric Determination of Trace Amounts of Arsenic In Sediment, Flyash and Water Samples
A simple, rapid, cost-effective spectrophotometric method is developed to determine arsenic in ppm levels. The present study is based on the reaction of arsenate with acidified molybdate and vanadate to form a molybdovanadoarsenate complex. The heteropoly acid complex formed interacts with cationic dye, Rhodamine B resulting in pinkcoloured ion-pair complex whose absorbance is measured at 590 n...
