Abstract:

Characteristics of absorption of activated carbon on methylene blue were studied. It was demonstrated that adsorption of activated carbon on methylene blue was very stable on monomolecular adsorption and when multimolecular adsorption existed adsorption became to be weak. An improved method was suggested that many samples were tested adsorption of activated carbon on methylene blue in parallel experiment and certain sample was selected to use in next experiment, its color should approximate to the color of 0.4% CuSO4 but darker slightly and activated carbon loaded methylene blue was added some

Abstract:

Background Hypocalcemia is a common complication of thyroidectomy resulting from an injury to the parathyroid gland. Methylene blue, which is a medication and dye that has been used for more than a century, is safe and readily available. The previous study has found that methylene blue spray on the surgical field is absorbed by the parathyroid gland faster than in the perithyroidal area. This study was aimed to evaluate the diagnostic value of methylene blue spray to identify the parathyroid gland during thyroid lobectomy. Methods Patients who underwent thyroid lobectomy were recruited. After

Abstract:

A MoS2/TiO2 composite was synthesized and its photocatalytic activity for the degradation of methylene blue was evaluated. The results showed that the nano-MoS2/TiO2 composite presented excellent photocatalytic properties in the degradation reaction of methylene blue, which was ascribed to the good absorption of nano-MoS2/TiO2 in the visible light region. The decoloration rate of methylene blue solution was influenced by the dosage of nano-MoS2/TiO2 and the initial concentration of methylene blue. However, both the pH value and the degradation temperature had negligible effects on the decolora

Abstract:

Mesoporous silica microspheres (MSM) with diameter about 100 nm were prepared by hydrothermal synthesis using cetyl trimethyl ammonium bromide(CTAB) as template agent and tetraethyl orthosilicate(TEOS) as silica source. And they were characterized byscanning electron microscopy (SEM) , N2 adsorption-desorption analysis , infrared spectroscopy (FT-IR). Then methylene blue adsorption test was investigated. Effect of pH, temperature of the adsorption of methylene blue onto MSM were studied. The adsorption amount onto MSM increased with the initial pH-value of the solution in the range of 3~10. Al

Abstract:

Methylene blue simulated wastewater was treated with a UV-H2O2 combined system. Influences of factors such as reaction time, initial pH value and H2O2 dosage were investigated, and the reaction kinetics of the process was explored. Results showed that the degradation of methylene blue happened only in the presence of both conditions: UV irradiation and H2O2 addition. Initial pH and H2O2 dosage had a remarkable influence on the degradation efficiency. Through several groups of univariate experiments, the optimum pH and H2O2 dosage of the photolysis process were found to be 4–5 and 0.165 mL 30%
