the nano sized tio2 and zno are the most active photocatalysts. methylene blue was used as a reference molecule for the photocatalytic degradation. the tio2 and zno can totally remove methylene blue dye. the effect of various process parameters like initial concentration, contact time, dose of catalyst and ph on the extent of removal of dye by photocatalysis in presence of tio2 and zno was stu...
BACKGROUND The use of a dye and radiocolloid to detect sentinel lymph nodes in breast cancer increases the detection rates. However the use of either method alone does not modify the false negative rate. Therefore there is no formal contraindication for the exclusive use of dye to detect nodes. AIM To report a prospective analysis of the exclusive blue dye technique for sentinel node biopsy i...
BACKGROUND In early breast cancer, the optimal technique for sentinel lymph node biopsy (SLNB) is the combined technique (radioisotope and Patent Blue V) which achieves high identification rates. Despite this, many centres have decided to stop using blue dye due to blue-dye-related complications (tattoo, anaphylaxis). We evaluated the SLNB identification rate using the combined technique with a...
BACKGROUND There is now increasing evidence to support the use of indocyanine green (ICG) for sentinel lymph node (SLN) detection in early breast cancer. The primary objective of this feasibility study (ICG-10) was to determine the sensitivity and safety of ICG fluorescence imaging in sentinel lymph node identification when combined with blue dye and radiocolloid. METHODS One hundred women wi...
Article history: Received on: 10/11/2016 Accepted on: 11/12/2016 Available online: 27/02/2017 Six fungal species were isolated from Egyptian soil and identified as Aspergillus flavus, Aspergillus niger, Penicillium canescens, Penicillium crustosum, Penicillium sp. and Fusarium sp. and were tested for their decolorization activity of direct blue dye (DB). Aspergillus flavus and Penicillium canes...
background; recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. therefore, the aim of this study was to determine the feasibility of using lemna minor for acid blue 292 (ab292) dye removal from aqueous solution and to determine the optimal conditions. methods; this experiment...
the use of orange peel as low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. this paper concerns with the removal of blue 56 from aqueous solutions by orange peel. the effects of ph , initial concentration, adsorbent dosage, and particle size of adsorbent, temperature and also isotherm data analys...
background dyes are one of the most important industrial pollutants, especially in textile industries. many methods have been proposed in order to remove color from wastewater among which, adsorption is more acceptable due to the ability for its use in the large scale. objectives the objective of this study was to investigate pumice as an inexpensive adsorbent for removal of methylene blue from...
Methylene blue was efficiently removed from aqueous solution by foam flotation using a rhamnolipid a biosurfactant as a dye collector. The effects of four parameters, namely, pH (1.5–11.5), frother concentration (5–65 ppm), aeration rate (2–6 L/min) and rhamnolipid to methylene blue weight ratio (0.5–6.5), on dye removal were studied and optimized using response surface methodology. Results...
