Titrimetric and Spectrophotometric Determination of Tinidazole Tablets
A simple, sensitive, rapid, reproducible, economical and easily accessible method for the determination of tinidazole tablets is described. From the experiment carried out there is the need for recrystallisation of tinidazole tablet before it is analysized. Ultraviolet (UV) absorption analysis corresponds to the result obtained with non-aqueous titration. And the best solvent to be use for non-...
متن کاملTitrimetric and spectrophotometric determination of lamivudine in pharmaceuticals
Three new methods are described for the assay of lamivudine in bulk drug and in tablet dosage forms using chloramine-T and two dyes, methyl orange and indigo carmine, as reagents. In titrimetry, aqueous solution of lamivudine is treated with a measured excess of chloramine-T in sulphuric acid medium and after the oxidation of lamivudine is judged to be complete, the unreacted oxidant is determi...
متن کاملSimultaneous titrimetric determination of bicarbonate and titratable acid of urine.
An acid-titration method for the determination of bicarljonate and titratable acid in the one sample of urine is described. The method needs only one manipulation of the sample of urine, and was devised to simplify routine laboratory methodology. The accuracy and precision of the urinary bicarbonate method during routine laboratory use is comparable to that obtained by using the Van Slyke manom...
متن کاملThe Titrimetric Determination of “lactobacillus Case1 Factor” and “folic Acid”*
Microbiological tests have aided greatly in the isolation work on “L&o!x~ciZZus casei factor,” demonstrated by Snell and Peterson in 1940 (l), and “folic acid,” the nutrient required by Streptococcus lactis R as defined by Mitchell et al. (2). It seems likely that bacterial assays will continue to play an important role in the study of these compounds, since development of chemical methods has ...
متن کاملDirect titrimetric determination of fluoride in natural waters.
The fluorine content of drinking waters has become a matter of great interest to those concerned with the control and diminution of dental caries. In the U.S.A. many are of the opinion that the epidemiological studies of Dean (1938) and his co-workers (Dean, Arnold & Elvove, 1942) provide convincing evidence for the belief that, within certain limits, there is an inverse relationship between th...
