Ascorbic acid is used for treatment in hypovitaminosis, nutritional deficiency, scurvy, gingivitis, Barlow and Basedow diseases. In this study, a simple sensitive kinetic spectrophotometric method was developed the determination of ascorbic Eruca sativa. The rate formation product formed as result reaction with iron (III) sulfate phenanthroline reagents determined by measuring absorbance at 510...

We describe a new kinetic method for potentiometric determination of creatinine in serum, based on the creatinine--picrate reaction in alkaline medium (Jaffé reaction). The reaction is monitored with a picrate-selective electrode, and the increase in electrode potential during 270 s is measured and related directly to the creatinine concentration. Small cation-exchange columns are used to separ...

The objective of this research was to develop a kinetic-spectrophotometric method for the determination microquantities L-histidine in pure form and dietary supplements. based on kinetics ampicillin degradation by Ni(II) ion as catalyst presence strongly alkaline medium. rate reaction monitored spectrophotometrically measuring increase absorbance at 265 nm function time. same approach used inve...
