Immobilization of Ligands on Surfactant Coated Alumina for Removal of Cations
In this research new adsorbents were prepared by modification of surfactant-coated g-alumina with three ligands; 1-(2-pyridylazo)-2-naphtol (PAN), dithizone (HDZ) and dimetyl golyoxime (DMG). The adsorbents were used for removal and pre-concentration of Pb+2, Cd+2, Ni+2, Cu+2, Co+2. Aqueous solutions of the me...

ساخت الکترودهاِی اصلاح شده ِیکِی از چالشهاِی همِیشگِی در دانش شیمِی بوِیژه شیمِی تجزیه مِی باشد ،که با در نظر گرفتن سادگِی ساخت، کاربردی بودن و ارزان بودن روش مِی توان به باارزش بودن چنِین سنسورهاِی پِی برد.آنچه که در ادامه آورده شده به ساخت و کاربرد الکترودهاِی اصلاح شده با استفاده از نانو ذرات در اندازه گِیرِی ولتامترِی آهن وکادمِیم اشاره دارد. کار اول اختصاص دارد به ساخت الکترود خمِیر کربن اصلاح شده با لِیگاند داِ...
15 صفحه اولfabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
Extraction sorbent with nanographene with aminopropyltriethoxysilane for the preconcentration (APTES) on surfactant coated C18 of Cd(II) in water
Solid phase extraction (SPE) or liquid-solid extraction is poplar and growing techniques that areused to sample preparation for analysis. Metal nanoparticles have been studied for decades, and this is due to the properties that these materials do not have in bulk state. In nanoscale materials, the numbers of surface atoms is high and hence, have significant surface effects. A novel, simpl...
