A New Visible Spectrophotometric Approach for Mutual Determination of Amoxicillin and Metoclopramide Hydrochloride in Pharmaceuticals After Cloud Point Extraction

Development and Validation of the Simple and Sensitive Spectrophotometric Method of Amoxicillin Determination in Tablets using Sulphanilamides

“…On the other hand, the colored amoxicillin derivatives as analytical forms for AM spectrophotometric determination are often obtained using the azo-coupling reaction. In particular, the spectrophotometric methods of AM determination, which are based on their reaction with diazotized p-aminobenzene acid and procaine, 23 o-nitroaniline, 24 metaclopramid, 25 benzocaine, 26 and sulphanilic acid 27 are known. The spectophotometric methods of the AM determination based on the reactions of chelate and ion-pair complexes formation 24,28,29 are described.…”

“…However, many of the known methods of AM determination have a number of disadvantages: long run time, use of organic solvents, and a boiling/ice water bath. All of the above spectrophotometric methods [23][24][25][26][27][28][29] of AM determination were used only for the analysis of pharmaceutical formulations. Moreover, many of the described spectrophotometric methods for AM determination are not validated, although it is required by most world's pharmacopoeia.…”

Eco-Friendly Adsorption of Cationic (Methylene Blue) and Anionic (Congo Red) Dyes from Aqueous Solutions Using Sawdust

“…This method is widely used due to its effectiveness in selectively eliminating pollutants such as industrial dyes, medications, and heavy metals. Among these, dyes are particularly concerning as they are detrimental to both animal and human health, and their release into aquatic solutions can have severe environmental effects [1][2][3][4][5][6]. A common substance used in adsorption technology is activated carbon, prepared from readily available and inexpensive agricultural waste.…”

A New Approach for the Voltammetric Determination of Amoxicillin in the Dosage Form Using Azo Coupling Reaction with Sulphanilamide

“…The development and adoption of new techniques for the determination of biologically active compounds in more effective combination drugs still remains one of important tasks of modern analytical and pharmaceutical chemistry. The methods of high performance liquid chromatography [6][7][8][9][10][11] and spectrophotometry [1][2][3][12][13][14][15] are often suggested for the quantitative determination of amoxicillin. The first one is a time-consuming and expensive method and the second is not a sufficiently selective and sensitive method.…”
