Use of ceric ammonium sulphate and two dyes, methyl orange and indigo carmine, in the determination of lansoprazole in pharmaceuticals.
Two spectrophotometric methods are proposed for the assay of lansoprazole (LPZ) in bulk drug and in dosage forms using ceric ammonium sulphate (CAS) and two dyes, methyl orange and indigo carmine, as reagents. The methods involve addition of a known excess of CAS to LPZ in acid medium, followed by determination of residual CAS by reacting with a fixed amount of either methyl orange, measuring t...
متن کاملKinetic isotope effect on the proton-transfer in indigo carmine
We have found that photo-excited indigo carmine causes stepwise proton transfer to generate monoalcohol intermediate, which immediately returns to the parent molecule [I. Iwakura, A. Yabushita, T. Kobayashi, Chem. Lett. 38 (2009) 1020]. The kinetic isotope effect in the proton transfer of this system has been studied by direct observation of the real-time molecular vibrational amplitude during ...
متن کاملCore-Shell MnO2-SiO2 Nanorods for Catalyzing the Removal of Dyes from Water
This work presented a novel core-shell MnO2@m-SiO2 for catalyzing the removal of dyes from wastewater. MnO2 nanorods were sequentially coated with polydopamine (PDA) and polyethyleneimine (PEI) forming MnO2@PDA-PEI. By taking advantage of the positively charged amine groups, MnO2@PDA-PEI was further silicificated, forming MnO2@PDA-PEI-SiO2. After calcination, the composite MnO2@m-SiO2 was final...
متن کاملThe use of indigo carmine for dye dilution curves.
Investigation of the properties of indigo carmine reveals that it may be more suitable than the dye, T-1824, for circulator}' studies that are now commonly carried out using the dye dilution principle of Stewart and Hamilton. Comparison is made of simultaneous dilution curves of indigo carmine and radioactive iodinated serum albumin. Apparently, indigo carmine is bound to protein firmly enough ...
متن کاملIndigo carmine-induced hypotension in patients undergoing general anaesthesia.
Indigo carmine is a blue dye that is widely applied to localise ureteral orifices. It is generally believed to be a safe, biologically inert substance, and hypotensive reactions are extremely rare. However, we experienced three cases of indigo carmine-induced hypotension within a period of two weeks.
