[ 1 ] - Fabrication of an Electrochemical Sensor Based on a New Nano-ion Imprinted Polymer for Highly Selective and Sensitive Determination of Molybdate

In this work a new chemically modified carbon paste electrode was constructed for accurate, simple, sensitive and selective determination of molybdenum (VI) ions. The results of modified electrode by an ion imprinted polymer were compared with those obtained with carbon paste electrode. The results showed the stripping peak currents had a dramatic increase at the modified electrode. Under the o...

[ 2 ] - A Method Based on Ultrasound-assisted Solidification of Floating Drop Microextraction Technique for the Spectrophotometric Determination of Curcumin in Turmeric Powder

A method based on the ultrasound-assisted solidification of floating drop microextraction technique was developed for the spectrophotometric and spectrofluorimetric determination of curcumin in turmeric powder. In this work a small volume of an organic solvent was floated on the surface of an aqueous solution. After sonication the organic solvent is solidified and separated. The effect of extra...

[ 3 ] - A sensitive method for electrochemical determination of molybdenum (VI) in plant foodstuff samples using Ni0.5Zn0.5Fe2O4 nanocomposite modified carbon paste electrode

In the present study, a new chemically modified carbon paste electrode (CPE) is constructed for rapid, accurate, simple, highly sensitive, and selective determination of Mo (VI) using differential pulse voltammetry. The electrode was prepared using magnetic nickel zinc ferrite nanocomposite (Ni0.5Zn0.5Fe2O4), as the modifier in CPE (Ni0.5Zn0.5Fe2O4/CPE). Mo (VI) was determined after preconcentr...
