Modified determination of total and inorganic mercury in urine by cold vapor atomic absorption sectrometry.
In this procedure a single-beam spectrophotometer is used without background correction. By the method of Magos [Analyst (London) 96, 847 (1971)] mercury in undigested urine is complexed to L-cysteine in acid solution. At high pH and in the presence of stannous ions, mercury ions are reduced to elemental mercury. The mercury vapor is partitioned above the reagent solution in a specially designe...
متن کاملA sequential injection cold-vapor atomic absorption method for the determination of total mercury.
A sequential injection (SI) method for the determination of mercury via cold vapor atomic absorption spectrophotometry is presented. The method differs from flow injection (FI) cold vapor methods for the determination of mercury because of the simplicity of the system required for the method: one pump, one valve, a gas-liquid separator, and an atomic absorption spectrophotometer equipped with a...
متن کاملCold Vapor Atomic Absorption Determination of Hg in Crude Oil and Gasoline Samples after Solid Phase Extraction Using Modified Disks
A facile and highly efficient method have been developed for the preconcentration of the mercury content in crude oil and gasoline samples after digestion with microwave-assisted digestion. Octadecyl silica membrane disk has been modified by the recently synthesized triazene ligand, (E)-1-(2-ethoxyphenyl)-3-(4-nitrophenyl) triaz-1-ene (ENT), then the modified membrane was used for the preco...
متن کاملAutomated microwave digestion of certifiable color additives for determination of mercury by cold vapor atomic absorption spectrometry.
A procedure using an automated microwave flow digestion technique was developed and validated for the digestion of samples of certifiable color additives before mercury determination by cold vapor atomic absorption spectrometry. Recovery studies were performed by spiking most of the color additives subject to batch certification by the U.S. Food and Drug Administration with inorganic mercury (H...
متن کاملAnalysis of Total Mercury in Chinese Spice Mixtures using Flow Injection Cold Vapor Atomic Absorption Spectrophotometry
Spices are often used as dietary components to improve color, aroma, palatability and acceptability of food. Most spices are fragrant, aromatic and pungent.1 Spices and herbs, grown widely in various regions of the world, have been used for several purposes since ancient times – in folk medicine as antiscorbutic, antispasmodic, tonic, carminative agents against bronchitis, ulcers and as diureti...
