NANO-STRUCTURED VERMICULITE CLAY FOR HIGH-PERFORMANCE ADSORPTION OF MALACHITE GREEN DYE: STRUCTURAL CHARACTERIZATION AND REGENERATION POTENTIAL

Aseel M. Aljeboree1, Ali Fawzi Al-Hussainy2, Usama S. Altimari3, Shaima Abd4, Zainab A. Alhassan5, Ayad F. Alkaim1

This study employed nanoclay as a low-cost, environmentally friendly adsorbent for the effective removal of malachite green (MG) dye from aqueous solutions. The nanoclay was characterized using XRD, FESEM, TEM, TGA, and FTIR. Structural and morphological analyses confirmed a porous, multilayered structure that was enhanced…

INDIRECT SPECTROPHOTOMETRIC DETERMINATION OF AMOXICILLIN TRIHYDRATE IN PURE FORM AND IN PHARMACEUTICAL PREPARATIONS USING CRESOL RED DYE

Raghad Sh. Al-Sanjary*, Mohammed S. Al-Enizzi

Abstract: A rapid, sensitive, and indirect spectrophotometric method was developed for the determination of amoxicillin in pure form and in pharmaceutical preparations. The method is based on the oxidation of the pharmaceutical compound amoxicillin in an acidic medium (hydrochloric acid) with a known excess of…

INDIRECT SPECTROPHOTOMETRIC DETERMINATION OF THE ATENOLOL BY USING TOLUIDINE BLUE DYE

Anfal A. Mohammed and Zeena Z. Al Abdali*

Abstract: An efficient and eco-friendly indirect spectrophotometric method has been devised to determine the amount of atenolol in both pure form and in tablet formulations. This method relies on the oxidation of atenolol using an excess of standard potassium permanganate in an acidic medium. The…

INDIRECT SPECTROPHOTOMETRIC DETERMINATION OF MEBENDAZOLE VIA OXIDATION-INDUCED DECOLORIZATION OF NEUTRAL RED DYE: APPLICATION TO PHARMACEUTICAL TABLETS AND HUMAN SERUM

Zahraa A. Alrassam, Othman N. Sabeeh

Abstract: The aim of this method is to develop a simple, accurate, sensitive, inexpensive, indirect spectrophotometric assay of mebendazole in pharmaceutical formulation (tablets) and pure form. The suggested technique relies on the oxidation of mebendazole by the addition of a known excess amount of calcium…
