Simple, rapid, and extractive spectrophotometric methods were developed for the determination of gatifloxacin (GT) in bulk and pharmaceutical dosage form. These methods are based on the formation of yellow ion-pair complexes between the basic nitrogen of the drug and three sulphonphthalein acid dyes, namely; bromocresol green (BCG), bromocresol purple (BCP), bromophenol blue (BPB) and bromothym...

The NAD-dependent isocitrate dehydrogenase [threo-D(S)-isocitrate:NAD(+) oxidoreductase (decarboxylating); EC 1.1.1.41] from pig heart is a multisubunit enzyme with a molecular weight of approximately 340,000. Electrophoresis of the enzyme in 10% polyacrylamide gels containing sodium dodecyl sulfate reveals two discrete bands with molecular weights of 41,000 and 39,000. The two bands exhibit ap...

In this study, we aimed to observe how different operating parameters influenced the photocatalytic degradation of rhodamine B (RhB, cationic dye) and bromophenol Blue (BPB, anionic over ZnO/CuO under visible light irradiation. This further corroborated optimization study employing response surface methodology (RSM) based on central composite design (CCD). The synthesis nanocomposite was carrie...

Electrocoagulation (EC) in a batch cell with Al anode and Fe cathode in monopolar parallel (MP) connection was used for the removal of basic dye, Bromophenol Blue (BPB). The effects of current density, pH, temperature and initial dye concentration, on the process were investigated. Equlibrium data were analyzed using four model equations: Langmuir, Freudlinch, Temkin and Dubinin–Radushkevich. D...

Abstract In this research, zinc oxide nanoparticles (ZnONPs) were prepared via a facile one-pot chemical precipitation approach and applied in the adsorption of bromophenol blue (BRB) as antifungal agents against filamentous fungi plant pathogens; Alternaria alternata CGJM3078, CGJM3006 Fusarium verticilliodes CGJM3823. The ZnONPs characterized by UV–Vis, FTIR, XRD, TGA, BET, SEM, TEM, EDX tech...

The black cutworm, Agrotis ipsilon larvae is the most serious pest around world; it attacked plant in growing stage of many crops such as cotton, potato, corn, and tomato causing great damage for them others which led to reduce yield. So chemical insecticides are used controlling this may buildup resistance these pesticides Therefore, needed evaluate some compounds that belonged different categ...

It is difficult to directly determine the quantity of cationic finishing agents on surface cellulosic fabrics. Herein, we report a direct and feasible method by Kubelka–Munk equation quantify poly (hexamethylene biguanide) hydrochloride (PHMB) adsorbed onto cotton fabrics based principle formation stable blue dye between PHMB bromophenol sodium (BPB). The adsorption was first investigated maxim...

A series of bromophenol hybrids with N-containing heterocyclic moieties were designed, and their anticancer activities against a panel of five human cancer cell lines (A549, Bel7402, HepG2, HCT116 and Caco2) using MTT assay in vitro were explored. Among them, thirteen compounds (17a, 17b, 18a, 19a, 19b, 20a, 20b, 21a, 21b, 22a, 22b, 23a, and 23b) exhibited significant inhibitory activity agains...
