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 اولSPECTROPHOTOMETRIC STUDY OF THE STOICHIOMETRY AND CONDITIONAL STABILITY CONSTANTS OF SOME TRIVALENT METAL ION COMPLEXES OF METHYLTHYMOL BLUE
Complexation reactions between methylthymol blue and Fe , A l ,Ga , 1n a nd TI ions have been studied in buffer aqueous solutions of pH 5.0 at 2S°C by a spectrophotometric technique. The conditional stepwise stability constants of the resulting 1:l and 1:2 (metal-to-ligand) complexes were determined from the absorbance-mole ratio data at three different wavelengths of the visible sp...

The stability constants of the complexes of Cu (II), Co (II) and Ni (II) ions with 3-(3’-nitrophenyl)4-(4"-chlorobenzoyl)-5-(2-hydroxyphenyl) pyrazole (L1), 3-(4’-chlorophenyl)-4-(4"-chlorobenzoyl)-5-(2hydroxyphenyl) pyrazole (L2), 3-(4’-methoxyphenyl)-4-benzoyl-5-(2-hydroxyphenyl) pyrazole (L3), 3(4-bromophenyl)-4-furoyl-5-(2-hydroxyphenyl) pyrazole (L4) have been determined by the pH-metric m...
متن کاملThe nonenzymatic activation of acetate by adenosine triphosphate-bivalent metal chelates.
reaction, which occurs under mild conditions and at low concentrations of reactants, is absolutely dependent on the presence of bivalent metal ions, and is stimulated by univalent metal ions. The most effective bivalent metal ion was found to be Ca++. When Mn++ ion was used to satisfy the bivalent metal ion requirement, the most effective univalent metal ion was found to be Kf. The reaction was...
