I N RECENT REPORT5 (1-3) we have fully described a heat clot-extraction technic for the separation of low molecular weight, water-soluble constituemits of serum froni serum proteimis. The present communication outlines applicatiomi of thatmethod, to the simultaneous determination of sodium, potassium, chloride, glucose, and urea nitrogen from a single 0.1-ml. serum sample without the use of ult...

Diphenylcarbazone has been used for the simultaneous and individual determination of zinc(II) and cadmium(II) at trace levels. The carbazone complexes of zinc(II) and cadmium(II) at pH 7–10 are pink in color, and are soluble in TX-100 micellar media. Under optimum conditions, calibration graphs for individual and simultaneous determination by first, second, third and fourth derivative spectroph...

Abstract: Bagasse is a solid waste from the sugar cane milling process in industry. The can be used as an ingredient making silica gel which functions adsorbent. This done by changing its chemical structure composition to increase role and function. study aims determine characteristics of synthesized bagasse (Saccharumofficinarum L.) modified using diphenylcarbazone much 0.24 g with sol-gel tec...

A sensitive micromethod for the colorimetric determination of free fatty acids (FFA) in plasma has been developed. FFA are extracted with chloroform-heptane-methanol with silicic acid being added to eliminate interfering phospholipids. Diphenylcarbazide containing diphenylcarbazone has been chosen as color-developing reagent, since the chromophore formed in the presence of FFA-Cu complex is sta...
