Potentiometric titration of sulphate, sulphite and dithionate mixtures, with use of a lead ion-selective electrode.

Simple methods are described for the analysis of sulphate, sulphite and dithionate mixtures by potentiometric titration with lead perchlorate (and use of a lead ion-selective electrode). The error and precision are both about 2-5% for the sulphate concentration range 3 x 10(-3) -6 x 10(-4)M. The sulphur content in fuels derived from refuse was determined by potentiometric titration after bomb-c...

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Antagonism between cadmium and magnesium: a possible role of magnesium in therapy of cadmium intoxication.

One of the important mechanisms of cadmium (Cd) toxicity is its interactions with bioelements, including magnesium (Mg). Exposure to Cd leads to disturbances in Mg metabolism in the organism, while Mg supplementation has an adverse effect on Cd absorption, accumulation and toxicity. According to the available results, which indicate a protective role of Mg against Cd toxicity, it remains to be ...
