objective: in order to overcome the limitation of systemic administration of methylene blue, this study investigated the encapsulation of methylene blue in polymeric liposomes and drug release following sonication. methods: we encapsulated methylene blue into nanoliposomes. the dynamic light scattering (dls) method was used to measure the size distribution of the liposomes. after loading methyl...

immobilization of catalysts on the surface of some inert supports makes therecovering step easier. because of the specific physicochemical properties, zeolites are good candidate as catalyst supports. in this study, zeolite x was synthesized by natural kaolin and tio2 was incorporated into zeolite phase by impregnation method. degradation of safranin orange, methylene blue and 2,4–dinitroanilin...

One of the famous dyes is methylene blue (MB) which is a symbol of hazardous dyes. In this research, methylene blue was adsorbed using the blends of saffron petals with activated carbon. Five independent variables involving pH (2-13), contact time (5-270 min), saffron petals powder dosage (0.1-10 g/l), initial concentration of methylene blue solution (20-300 ppm) and activated carbon dosage (0....

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 o...

introduction methylene blue was first described for the treatment of methemoglobinemia but practical usage of the compound for surgical purpose is common. the aim of this report is to describe a case of hemolysis in neonatal period as a potential hazard of methylene blue toxicity without presence of g6pd deficiency. case presentation in october 2015, a 36-week ga female infant with 2.05 kg weig...

methylene blue is widely used in various industrial branches. due to insufficient treatment, its occurrence in wastewater is frequently detected, which may result in serious environment problems to aquatic organisms. hydroponic experiments were conducted with rice seedlings (oryza sativa l. cv. xzx 45) exposed to methylene blue to determine the effective concentration using relative growth rate...

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...
