Coloring substances in food are generally classified into two categories, namely natural dyes and synthetic dyes. Rhodamine B is a dye which widely used the textile industry. The use of can cause irritation to digestion, inhalation, eyes. This research was conducted detect rhodamine content tomato sauce by adding detergent. design this study qualitative descriptive on market. test results for p...

In the acute respiratory distress syndrome, alveolar flooding by proteinaceous edema liquid impairs gas exchange. Mechanical ventilation is used as a supportive therapy. In regions of the edematous lung, alveolar flooding is heterogeneous, and stress is concentrated in aerated alveoli. Ventilation exacerbates stress concentrations and injuriously overexpands aerated alveoli. Injury degree is pr...

The induced flow effect is the rotary motion generated in the fluid flow due to the temperature gradient. The phenomenon of thermophoresis is the movement of particles from the warmer side of the fluid to the cooler side. Laser is a very suitable device for creating a temperature gradient due to its unique features such as high power density, harmonic waves, single wavelength and very low diver...

In this report, poly(1,8-diaminonaphthalene) as a molecularly imprinted polymer (MIP) coated on gold nanoparticles (nano Au) dispersed ITO electrode was prepared. While nano Au strongly enhance the Raman signal of analyte, MIP layer allows to selective trap and enrich analyte molecules close surface. fact, by building matrix around target molecules, in case is rhodamine B then extraction we can...

The present study describes the green synthesis of TiO2 nanoparticles using Sesbania Grandiflora and Solanum nigrum leaf extracts. characterisation synthesised is carried out XRD FTIR. photo catalytic degradation Rhodamine-B dye carry under sunlight irradiation by UV- Vis spectrophotometer. Among synthesized catalysts, SG/TiO2 was found to be best for photocatalytic dye. degraded water also tes...

Rhodamine B (Rh-B) is one of the most common pollutants in the effluents of textile industries effluents in developing countries. This study was carried out to evaluate the applicability of used black tea leaves (UBTL) for the adsorptive removal of Rh-B from aqueous system by investigating the adsorption kinetics in batch process. The effects of concentration and temperature on adsorption kinet...

Most of previous papers in the field of dye removal used one dye or dyes with nearly separate spectra that simplifies dyes concentration determination by Beer's law at different λmax. In many real situations, dyes with highly overlapped spectra exist and their concentrations can be determined by multivariate analysis methods. In this study, principal component-wavelet neural network (PC-WNN) wa...

Rhodamines, a group of excellent fluorophores, have been widely used to design various fluorescent probes; however, their maximum emission wavelengths are relatively short for bioimaging. Herein, we report new kind rhodamine derivatives characterized by the dibenzo[1,4]oxazepine core, which can selectively react with peroxynitrite (ONOO−), generating oxazines much longer analytical wavelengths....

Thermally stable, 3D rod-like, nanosized, pH-stable Fe–Al metal–organic-framework with terephthalic acid as a linker surface area 120.255 m 2 g −1 was synthesized solvothermally for fluoride adsorption and the photodegradation of rhodamine B/methylene blue (pH 2–11).
