متن کاملCatalytic determination of ultra trace amounts of tellurium by 2.5-order differential oscillopolarography.
A highly sensitive and selective catalytic method with 2.5-order differential oscillopolarographic detection is described for the determination of tellurium, based on its activation effect on the slow Pd(II)-catalyzed reaction of sodium hypophosphite and methyl red in hydrochloric acid medium at 100 degrees C. Methyl red exhibited a sensitive 2.5-order differential polarographic wave at -0.35 V...
متن کاملInstrumental Neutron Activation Analysis of Trace Elements in Some Food Spices Consumed In Tehran, Iran
Introduction There is a growing interest in determining the concentration of various elements in food spices. In the present study, the instrumental neutron activation analysis (INAA) was employed to measure the trace elements in 11 commonly food spices consumed in Tehran, Iran. Materials and Methods The levels of K, Mn, Na, Cl, V, Br, Al, and As were determined and their effects on human healt...
متن کاملKINETIC-SPECTROPHOTOMETRIC DETERMINATION OF TRACE AMOUNTS OF NITRITE BY THE REACTION OF METHYL ORANGE FORMATION
The composite diazotization coupling reaction of sulfanilic acid and N, Ndimethylaniline was used for the precise, accurate, and rapid determination of trace amounts of nitrite ion (0.02-3 µg/ml). The reaction was monitored spectrophotometrically by measuring the absorbance of the produced methyl orange at 510 nm by a fixed the method of 5.0 minutes. The relative standard deviation for the...
