Synthesis and application of chelating resins based on polyacrylonitrilediethylenetriamine for metal ions removal
Chelating resins based on polyacrylonitrile and diethylenetriamine (PAN-DTA) wereprepared through the simple reaction of polyacrylonitrile with various volume percents ofdiethylenetriamine (DTA), (25, 50, 75 and 100). The prepared resins were applied to removeheavy metal ions such as Cu(II), Zn(II) and Cd(II) from aqueous solutions. The sorptionbehaviors of the resins for these metal ions were ...

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 اولDirect evidence for two interaction modes in adsorption of divalent metal ions to iminodiacetate-type chelating resins.
The adsorption curves of divalent metal ions (M2+) to an iminodiacetate(IDA)-type chelating resin (-L2-) under the condition of metal ions in excess against IDA groups clearly indicated the difference in contribution between two species. Copper and nickel are adsorbed only as [(-L)M(II)], while cadmium and calcium are adsorbed as [(-L)M(II)] and [(-LH)2M(II)]. Addition of salts may enhance the ...
متن کاملChelating Agents and the Regulation of Metal Ions
Up to about the early 1980s it was perhaps still possible to summarize in a review of a moderate length the development of the medicinal applications of chelation chemistry and the exploitation of such chemistry in regulating the metal ion concentrations in the body. However, in the last few years there has a great surge in the development of chelation chemistry and its usage in medicine and re...
