p-Toluene-sulfonic acid, cholesterol determination, and explosions.
HAVE BEEN USING the method of Pearson, Stern, and McGavack (1) for the determination of cholesterol for some time. It has proved to be a convenient and accurate procedure and the reaction had always gone smoothly. One day recently, however, the tubes were set up for the determination as usual, using a freshly prepared solution of p-toluenesulfonic acid. Solutions made from the same bottle of so...
متن کاملEffect of Acid Treatment of Carbon Nanotubes on Their Adsorption Capacities of Benzene and Toluene
Toluene and benzene were eliminated using multi-walled carbon nanotubes (MWCNTs). In order to investigate influence of acid treatment on the MWCNTs adsorption capacities, the MWCNTs were functionalized by nitric acid (10 M) under reflux conditions for 2 h. Fourier transform infrared (FTIR) and Raman spectroscopy were employed to confirm the formation of functional groups on the nanotubes su...
متن کاملChemical doping of MoS2 multilayer by p-toluene sulfonic acid
We report the tailoring of the electrical properties of mechanically exfoliated multilayer (ML) molybdenum disulfide (MoS2) by chemical doping. Electrical charge transport and Raman spectroscopy measurements revealed that the p-toluene sulfonic acid (PTSA) imposes n-doping in ML MoS2. The shift of threshold voltage for ML MoS2 transistor was analyzed as a function of reaction time. The threshol...
متن کاملRemoval of Chromium from Chromium(VI) Solutions by Adsorption and Reduction Using Immobilized Persimmon Gel
The removal of chromium(VI) from an aqueous solution using persimmon gel was examined. The amount of chromium(VI) removed was strongly affected by the pH of the solution, with all chromium(VI) being removed at pH 2 or lower. However, in a solution containing, 15 mg dry weight of immobilized persimmon gel, the amount of removed chromium(VI) decreased as the pH increased. A part of chromium(VI) w...
