[ 1 ] - Formaldehyde measurement based on its electrocatalytic oxidation by Ni-TiO2 nanoparticles/chitosan modified carbon paste electrode as an effective method
In this work, for the first time, a new and effective bulk modified carbon paste electrode (CPE) was prepared by TiO2 nanoparticles and chitosan and then Ni2+ ions were incorporated to this electrode by immersion of the modified electrode in nickel chloride solution. The values of electron transfer coefficient, charge-transfer rate constant and electrode surface coverage f...
[ 2 ] - Simultaneous Adsorptive Stripping Differential Pulse Voltammetric Measurements of Trace Lead, Cadmium and Nickel in the Presence of 2-aminobenzoic Acid
In this study, 2-aminobenzoic acid (ABA) has been used as complexing ligand for simultaneousdetermination of metal ions by adsorptive cathodic stripping voltammetry (AdCSV), for the firsttime. Thus, a selective and sensitive procedure was presented for simultaneous determination oflead, cadmium and nickel using ABA and differential pulse-adsorptive cathodic strippingvolt...
[ 3 ] - A strategy for degradation of 2,5-dichlorophenol using its photoelectrocatalytic oxidation on the TiO2/Ti thin film electrode
In this work, the photoelectrocatalytic (PEC) degradation of 2,5-dichlorophenol can be used for its removal from aqueous solution. To study this activity, a TiO2 thin film modified titanium sheet (TiO2/Ti) was fabricated by anodizing Ti plates using a two electrode system under the constant bias voltage of 20 V for 20 min in a solution of 0.2% (v/v) HF followed by calcinat...

[ 5 ] - اندازه گیری ولتامتری غیرمستقیم یون +Zn2 توسط الکترود خمیر کربن اصلاح شده با چیتوسان و فروسیانید
در این کار تحقیقاتی، یک الکترود خمیر کربن اصلاح شده با چیتوسان و فروسیانید برای اندازه‌گیری ولتامتری غیرمستقیم یون Zn2+ به کار گرفته شده است. برای تهیه این الکترود اصلاح شده، ابتدا، الکترود خمیر کربن اصلاح شده با چیتوسان (Ch/CPE) از طریق مخلوط نمودن نسبت مشخصی از پودر گرافیت، روغن پارافین و چیتوسان تهیه شد. سپس، فروسیانید به ویژه از طریق جذب الکتروستاتیک و به صورت مدار باز در سطح Ch/CPE قرار گ...
