Study the effect of some solvents on the λmax and absorbance of bromo phenol blue and phenol red indicators

This study which carried out on some indicators including (Phenol red and Bromo phenol Blue). Different solvents were used including (Methanol, propanol, DMF and DMSO). The effect of solvents on the λ max and absorbance values were investigated. The results recorded that the λmax values were effected and changed according to the polarities of the applied solvents. Also, the obtained results showed changes in the absorbance values after applied solvents compared with the original absorbance values. Keywords: Bromophenol blue; Phenol red; Effect of solvents on electronic transitions

EFFICACY OF KOH AND LACTO PHENOL BLUE STAIN FOR EARLY DIAGNOSIS OF RHINOORBITOCEREBRAL MUCORMYCOSIS

BACKGROUND: Rhino orbito cerebral mucormycosis has emerged as a complication after covid infection and in immunocompromised nd patients after 2 wave of covid infection in April to July 2021. This complication needs to be diagnose as early as possible to halt its spread to important nasal and orbital strucures. AIMS: This study aim to detect the sensitivity of different primary microbiological stain like KOH and lacto phenol blue. OBJECTIVE: Objective of study is to compare the efcacy of different microbiological stain to detect mucormycosis METHODOLOGY: Retrospective observational study CONCLUSION:Lactophenol blue should be the rst laboratory investigations to detect mucormycosis with higher efcacy than KOH stain

Surface Modification of TiO2 @Pvc Composite Membrane for Textiledye House (Brome Phenol Blue) Filtration

The continued increase in the costs of chemicals, energy and water makes their recovery more important today than it was years ago when separation techniques by membrane filtration were first introduced to the textile industry. The aim of introducing membrane filtration is not only to reduce water consumption and wastewater streams. The paper describes the results of research works and implementation project concerning cleaner technology and water reuse in textile dye house by TiO2 @PVC composite membrane. Fabricated membranes were characterized with various analytical and experimental techniques. Results showed that the TiO2 blend TiO2 @PVC composite membrane were nano porous in nature with improved porosity and permeability. Addition of TiO2 improved the mechanical stability and water permeability of the composite membranes.TiO2 doped membrane showed better dye rejection behavior with a permeate flux. Size and charge based exclusions along with adsorption were identified as the separating principles. Fouling analysis clearly showed that TiO2 incorporated membranes possessed better antifouling effect than membrane without TiO2 .Thus the TiO2 blended TiO2 @PVC composite membrane are promising for the treatment of dye polluted wastewater.
