Gravimetric and Spectrophotometric Methods for the Determination of Piperazine. Picrolonic vs. Picric Acid
In the present work two new analytical methods, a gravimetric and a spectrophotometric, for the assay of piperazine free base and its soluble salts in the anthelmitic preparation "Oxyuran", are described. Both approaches are based on the quantitative reaction between the diprotonated cationic form of piperazine and the 3-methyl-4-nitro-1-p-nitrophenyl-5-pyrazolone (picrolonic acid), in sulfuric...
متن کاملSpectrophotometric Determination of Copper Piperazine Dithiocarbamate
Spectrophotometric method for determination of cu(II) in the trace quantities was developed by using piperazine dithiocarbamate as ligand in ammonium chloride-ammonium hydroxide medium at pH -9.5. The procedure developed was applied for the estimation of cu(II) in microgram quantities in the water samples and the method developed was found to be simple and sensitive. Spectrophotometry is one of...
متن کاملNear-infrared spectrophotometric determination of compositions of fullerene samples.
A novel method has been developed for the sensitive and accurate determination of compositions of fullerene samples. The method is based on the synergistic use of spectrophotometric measurements and partial least square method. The method is not only simple, inexpensive and fast but also is non-destructive. Compositions of various fullerene samples including fullerite which is the precursor to ...
متن کاملGravimetric determination of pipette errors
In chemical measurements (for instance in titrimetric analysis) it is very important to precisely measure amount of liquid, the measurement is performed with use of various measuring vessels. Presently laboratories use all kinds of glass measuring vessels like: beakers, flasks, etc., for measurement of bigger volumes of liquid, and in case of small volumes glass pipettes. Glass pipettes have be...
