The possible utilization of rice husk activated carbon as an adsorbent for the removal of methylene blue dye from aqueous solutions has been investigated. In this study, activated carbons, prepared from low-cost rice husk by sulfuric acid and zinc chloride activation, were used as the adsorbent for the removal of methylene blue, a basic dye, from aqueous solutions. Effects of various experiment...

Hydrogen peroxide is an important mild oxidant which is widely used in various applications including remediation of waste waters and drinking water resources. The safe level of H2O2 residue has to be controlled through accurate and precise measurement methods. A facile spectrophotometric method for the determination of hydrogen peroxide is based on the reaction of iodine ...

Methylene blue-treated fresh-frozen plasma (MB-FFP) is mainly used in Europe. The advantage of the methylene blue system is that units can be treated individually. The combined action of methylene blue and illumination is a photodynamic process preventing viral RNA and DNA replication. We report the first immediate allergic hypersensitivity reaction to methylene blue-treated plasma transfusion....

a simple, selective and sensitive method for the determination of trace amount of titanium (iv) based on its catalytic effect on methylene blue- ascorbic acid redox reaction has been reported. the reaction was followed spectrophotometrically by measuring the change in absorbance of methylene blue at 665 nm, 5 minutes after the initiation of the reaction. in this study experimental parameters we...

The investigation of complexes of ethidium bromide (EtBr) and methylene blue (MB) with DNA at 0.02 M Na ionic strength of solution has been carried out. Absorption and differential absorption spectra of EtBr and MB and their complexes with DNA were obtained. The isobestic point was revealed on the absorption and differential absorption spectra of EtBr and its complexes with DNA, while on analog...

The aim of this study was to compare and analyze the site-specific accuracy of mixture of lipiodol and methylene blue (MLM) (0.6 ml, 1:5) and pure methylene blue (0.5 ml) on the rabbit lungs. In this study, CT-guided percutaneous injection of MLM and methylene blue. Compare the staining degree by biopsy of lung tissue. Use 4 points system to evaluate the site-specific accuracy at 6h and 24 h af...

IN a previous communication [Boyland and Boyland, 1934] two distinct lactic dehydrogenases were described, one present in yeast and one in mammalian muscle. Tumour tissue (Jensen rat sarcoma) extracts made by the method previously used with muscle reduced methylene blue rapidly in the presence of lactic dehydrogenase coenzyme (prepared after Banga et al. [1932]) in the absence of any other subs...

The spinal cord injury (SCI) is a detrimental neurological disease involving the primary mechanical injury and secondary inflammatory damage. Curtailing the detrimental neuroinflammation would be beneficial for spinal cord function recovery. Microglia reside in the spinal cord and actively participate in the onset, progression and perhaps resolution of post-SCI neuroinflammation. In the current...

In the current situation of water shortage and serious pollution, plasma discharged technology has a useful application prospect in sewage treatment. order to control degradation rate pollutants, effects different gas environment, OH scavenger ethanol H 2 O on methylene blue simulated organic wastewater by assisted method were studied. The experimental results show that effect air discharge is ...
