A comparison has been made between reticulocyte preparations stained with purified azure B and with several commerically available batches of brilliant cresyl blue and new methylene blue. Marked variations were observed in the composition and staining performances of the various batches of the two commerically available dyes. Although there were no significant differences in reticulocyte counts...

UNLABELLED Location of the sentinel lymph node in malignant melanoma and early breast cancer patients requires separate injections of radiocolloid and blue dye. These agents are administered at alternative times because of their different rates of transit. This study has elucidated why particular dyes are absorbed by the lymphatic system from an investigation of dye molecular structure as a fun...

The adsorption of textile dyes by clay was investigated using basic dye (Methylene Blue). Adsorption of dye effluent onto clay samples was carried by batch studies at room temperature, 25oC. The effects of adding clay with zeolite, pH and shaking time towards adsorption performance were investigated. The results from the mixture of 1.0 g clay and 0.01 g zeolite, the increases of pH, pH 9 and th...

Methylene blue shows an isotope dependent triplet lifetime that is 50% longer in D(2)O compared with H(2)O as a result of electronic-to-vibrational relaxation. The effect is enhanced when the dye is bound to curcubit[7]uril due to a combination of restricted mobility and a unfavorable vibrational coupling.

Abstract Methylene blue dye discharged from the textile industries is a thiazine which toxic and non-degradable chemical. Activated carbon mostly used adsorbent to effectively remove industrial waste waters. Low-cost adsorbents like groundnut shell powder neem were for component level present in solution as batchmode treatment concentration of 200mg/litre fixed 0.5 grams Adsorbent I (Neem seed ...

Taguchi optimization method (L32 orthogonal array) was applied as an experimental design to determine optimum conditions for methylene blue dye removal from aqueous solutions by electrocoagulation (EC). Various electrocoagualtion parameters such as initial pH, time of electrolysis, concentration of dye, electrodes gap, applied current, solution temperature, amount of supporting electrolyte, des...
