Electrochemical study of anatase TiO2 in aqueous sodium-ion electrolytes

Published in Biointerface Research in Applied Chemistry

In this paper, a basic electro-analytical study on the behavior of anatase TiO 2 in aqueous NaOH has been presented using cyclic voltammetry technique (CV). The study has explored the possibility of using TiO 2 as anode material for ARSBs in presence of 5 M NaOH aqueous electrolyte. CV profiles show that anatase TiO 2 exhibits reversible sodium ion...

OXIDATION OF POLYETHYLENE GLYCOL-200 BY POTASSIUM PERIODATE IN ALKALINE MEDIUM: A KINETIC STUDY

Published in RASAYAN Journal of Chemistry

Kinetics of PEG-200 oxidation by potassium periodatewas studied in alkaline medium. First-order dependence of reaction on periodate was observed. Rate of the reaction was found to be independent of substrate concentration. An inverse fractional order with respect to alkaliwas shown. Arrhenius parameters were calculated. Rate law was postulated taki...

Kinetics of periodate oxidation of polyoxyethylene – 300, a biodegradable pharmaceutical polymer

Published in International Journal of Research in Pharmaceutical Sciences

Polyoxyethylene-300 (POE) is a well-known biodegradable pharmaceutical polymer. In order to understand the stability of POE and to derive the reaction rate law, the title reaction was carried out in aqueous alkaline medium. Reaction was found to be eirst order dependent on the concentration oxidant (periodate) and independent of substrate (POE) con...

Determination of Riociguat using Ninhydrin as a Chromogen

A simple method is described to determine the amount of riociguat in bulk and tablet formulation by visible spectrophotometry. Formation of a chromophore with max of 597 nm, due to the reaction between the aromatic amine groups present on riociguat and ninhydrin in citric acid medium forms the basis for the current method. Extension of conjuga...

Biowaste Material Utilization for Water Defluoridation & Statistical Investigation of Ground Water in Nalgonda District

Physicochemical parameters of ground water in Nalgonda District of Telangana (erstwhile a part of Andhra Pradesh), India were measured and analysed by statistical investigation. Activated carbons were prepared from bio-waste materials viz., Citrous nobilis, Bombax malabaricum, Pithacelobium dulce and Citrous limon sheaths (CNC, BMC, PDLC and CLC...
