Continuous flow method for measuring total alkaloid in tobacco or tobacco products

The invention provides a continuous flow method for measuring total alkaloid in tobacco or tobacco products. In the method, potassium thiocyanate and sodium dichloro isocyanurate are adopted to carry out reactions to generate cyanogen chloride on line. The cyanogen chloride can carry out reactions with total alkaloid (calculated in the form of nicotine) in tobacco or tobacco products to break off the pyridine rings of nicotine, and then further carries out reactions with p-aminobenzene sulfonic acid. The reaction products are measured by a chromometer at 460 nm. The method uses a buffer system to control the pH value of the reaction system in a range of 6.0 to 7.5, and the buffer system is composed of a buffer solution A and a buffer solution B. The buffer solution A is prepared by the following steps: weighing disodium hydrogen phosphate and trisodium phosphate, placing the weighed substances in a beaker, dissolving the substances with water, transferring the solution to a volumetric flask (1L), and adding water into the volumetric flask until the water reaches the scale. The buffer solution B is prepared by the following steps: weighing p-aminobenzene sulfonic acid, disodium hydrogen phosphate, sodium dihydrogen phosphate, and sodium citrate, placing the weighed substances into a beaker, dissolving the substances with water, transferring the solution to a volumetric flask (1L), and then adding water into the volumetric flask until the water reaches the scale.

Production formula for neutral chlorine dioxide powder (unitary package)

A disclosed production formula for a neutral chlorine dioxide powder (unitary package) contains: (1) 10-50% of a main agent (sodium chlorite); (2) 1-20% of an activator (citric acid, tartrate, boric acid and sodium bisulfate); (3) 2-30% of an activation auxiliary agent (sodium dichloroisocyanurate and sodium trichloroisocyanurate); and (4) 5-50% of an additive (sodium sulfate and sodium chloride); and (5) 10-40% of an assistant agent (anhydrous magnesium sulfate). The chlorine dioxide powder with different contents and different packaged forms can be prepared by physical mixing. When the chlorine dioxide powder is directly dissolved or diluted into a solution with a chlorine dioxide concentration of 200-250 mg / L, the pH value of the solution is closes to 7, and the solution is neutral. The technology of the invention does not belong to the prior art, and has great breakthrough and improvement on the prior art. The technology helps to creatively make up the disadvantage that conventional solutions with a chlorine dioxide concentration of 200-250 mg / L have a pH value of 1-3 and belong to acidic solutions or relatively strong acidic solutions, and helps to enable the chlorine dioxide solution to be neutral, and thus the chlorine dioxide solution possesses relatively wide application value.
