Simple Catalytic Currents at DME for Trace Amounts of Cerium(IV) in Water Samples
نویسندگان
چکیده
A catalytic polarographic method for the determination of microgram quantities of Ce(IV) is developed based on the catalytic currents of cerium(IV) in the presence of NH4Cl – NH4OH at pH 6.2 with piperazine. Piperazine produces catalytic current with Ce(IV) at peak potential -0.1 to -0.6 V vs. SCE. The procedure was applied for the estimation of Ce(IV) in water samples. The method is simple, sensitive and free from interference of many metal ions.

A NOVEL AND HIGHLY SENSITIVE CATALYTIC METHOD FOR THE DETERMINATION OF ULTRA TRACE AMOUNTS OF CERIUM WITH SPECTROPHOTOMETRIC DETECTION
Cerium (IV) has a catalytic effect on the very slow redox reaction between gallocyanine and bromate in acidic media. The reaction was monitored spectrophotometrically at 525 nm by a fixed time method of 4.0 rnin from initiation of the reaction. The decrease in absorbance at 525 nm is proportional to the Ce (IV) concentration in the range of 0.005-1.000 and 1.00-10.00 pg. ml-l. The limit of ...
