the preparation of polymer membrane selective to iron(ii) ion and its application to ion-selectiveelectrode is reported here. pvc membrane contains iron–selective n-phenylaza-15-crown-5 asionophore. the membrane electrode is highly selective to iron(ii) ion and exhibit good linearresponse over a wide concentration range of 1.0 × 10-2 to 1.0 × 10-6 m with nernstian slope of29.2 ± 0.6 mv per deca...
in this study, removal of methylene blue by electro-coagulation method using aluminum and iron electrodes was investigated. the influence of the operating parameters such as contact time, current density, anode type, inter-electrodes distance, initial and final ph and energy consumption rate was determined. dye removal was increased with increases in solution ph, current density and contact tim...
Introduction: For marketing and selling their products, water-treatment equipment vendors use commercial iron and aluminum electrodes thereby changing the quality of water and increasing soluble and suspended solids in water. Due to the lack of scientific justification for the creation of sludge and discoloration caused by water electrolysis with commercial electrodes, this study aimed to compa...

Background & Objectives: In this study, treatability of wastewater from a laundry unit was investigated by applying electrocoagulation method in which two pairs of aluminum and iron electrodes were utilized. Electrocoagulation is a noble treatment method suitable for different kinds of wastewater which has been given a considerable attentions by researchers recently. Applying direct current to ...
Large-scale high-energy batteries with electrode materials made from the Earth-abundant elements are needed to achieve sustainable energy development. On the basis of material abundance, rechargeable sodium batteries with iron- and manganese-based positive electrode materials are the ideal candidates for large-scale batteries. In this review, iron- and manganese-based electrode materials, oxide...
