The riot dyeing agent Rhodamine B is a loaded in ammunition, which can produce serious environmental pollution after use. In order to eliminate the of rhodamine B, decontamination method with simple operation, wide material sources and green environment protection was studied. First, an orthogonal experiment used obtain concentration ratio decontaminant excellent performance, that is, best effe...

This research focuses on the characteristics of polyvinyl alcohol and starch polymer blends doping with Rhodamine-B. The were prepared using solution cast method, which comprises 1:1(wt. /wt.). PVA had different ratios glycerin 0, 25, 30, 35, 40 % wt. ratio 30% wt was found to be most suitable mechanical properties by strength elasticity. blend 1:1 starch/PVA doped Rhoda mine-B dye 1, 2, 3, 4, ...

This study reports decolorization of Rhodamine B and Congo red by a partially purified laccase from Lentinus polychrous Lév. in the presence or absence of 2,2-azinobis (3-ethylbenzothiazoline-6sulfonate) diammonium salt (ABTS) as a redox mediator. The decolorization study showed that about 90% of Rhodamine B could be decolorized within 52 h, whereas Congo red could be decolorized more than 75% ...

A colorless and non-fluorescent rhodamine derivative, rhodamine B hydrazide (RH), is applied to detect nitric oxide and form fluorescent rhodamine B (RB). The reaction mechanism of RH with NO is proposed in this study. The probe shows good stability over a broad pH range (pH>4). Furthermore, fluorescence intensity of RH displays an excellent linearity to the NO concentration and the detection l...

Rhodamine B based fluorescence thermometry is commonly used in microfluidics to measure fluid temperatures in microchannels. Notable absorption of Rhodamine B into PDMS channel walls, however, causes difficulties in obtaining accurate temperature measurements due to a steady increase in the overall fluorescent signal. A simple and effective technique is reported that removes the fluorescent sig...

ABSTRACT: Activated carbon was developed from coconut shell, characterized and used for the removal of Rhodamine-B from wastewater successfully. The methylene blue number, iodine number and BET surface area of the prepared carbon were found to be 80 mg g, 600 mg g, and 1200 m g respectively. Rhodamine B is one of the water soluble, basic red cationic xanthene class dyes, a common water tracer f...

The intensity of two-photon-excited fluorescence measured relative to the intensity of hyper-Rayleigh scattering in the same apparatus was used to determine the two-photon-excited fluorescence cross sections of the xanthene dyes Rhodamine B, Rhodamine 6G, and Fluorescein. The measured cross sections at l0 5 1064 nm are s2PF (2) 5 1.5 6 0.3 3 10250 cm4 s, 2.0 6 0.4 3 10250 cm4 s, and 1.4 6 0.3 3...

The research of the present work was to investigate the removal of Rhodamine-B dye from aqueous solution by using Corchorus Olitorius-L Leaves Nano Carbon (ACONC). Generally, dyes are used in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Corchorus Olitoriu...
