TL;DR: In this article, a method for adopting crop stalks to prepare high-pure chlorine dioxide was described, in which the mixture was heated to 60 to 70 DEG C in water, the sulfuric acid of 1/1 isslowly added into the mixture while stirring, and then the chlorine dioxide is guided out under negative pressure and is absorbed by iced water; the catalyst is the complex-type ammonium citrate vanadyl.
Abstract: The invention discloses a method for adopting crop stalk to prepare high-pure chlorine dioxide The crushed and dried crop stalks and catalyst are added into the sodium chlorate solution and the mass ratio between the sodium chlorate, crop stalk and catalyst is controlled to be 10:120 to 220:001 to 010; then the reaction system is heated to 60 to 70 DEG C in water, the sulfuric acid of 1/1 isslowly added into the mixture while stirring, the reaction temperature is controlled to be 50 to 90 DEG C, the concentration of the sulfuric acid in the system is 45 to 80mol/L, and then the chlorine dioxide is guided out under the negative pressure and is absorbed by iced water; and the catalyst is the complex-type ammonium citrate vanadyl The reaction condition of the invention is gentle andthe reaction speed is quick; the reaction is stable and safe; the operation is convenient; the productivity of chlorine dioxide is high, the purity is high; and the manufacturing cost is low

TL;DR: In the deposition of zinc phosphate on steel arsenate ions are added to the phosphating solution as discussed by the authors, and the acid ratio should be within the range of 4:1 to 15:1, which can be adjusted by adding phosphoric, nitric or hydrochloric acids or zinc oxide or carbonate and sodium hydroxide.
Abstract: In the deposition of zinc phosphate on steel arsenate ions are added to the phosphating solution. In an example a concentrate of (parts per cent by weight): phosphoric acid 41.0, zinc oxide 8.3, sodium chlorate 10.8, nickelous nitrate hexahydrate 9.1, disodium arsenate (anhydrous) 0.25, water 30.55, is diluted with water and sprayed on the steel for one minute at 175 DEG F. The acid ratio should be within the range of 4:1 to 15:1. The ratio can be adjusted by adding phosphoric, nitric or hydrochloric acids or zinc oxide or carbonate and sodium hydroxide. The steel may be cleaned by tetrasodium phosphate and a wetting agent or trichloroethylene or perchloroethylene. The preferred ranges of the composition are (grams per litre): nickel 0.1-7, zinc ions 0.5-10, phosphate ions 2-20, nitrate ions 0.5-20, chlorate ions 0.5-15, arsenate ions 0.01-1.0. The arsenate may be in the form of arsenic acid, Na2HAsO4, NaH2AsO4, Na3AsO4, NaAsO4 or arsenic trioxide or pentoxide. The nitrate may be in the form of nitric acid, zinc, nickel or alkali metal nitrates.

TL;DR: In this paper, a sheet-type chlorine dioxide gas generant, which comprises a ventilation bag, is used to prevent corrosion and refreshing of fruits and vegetables in the packaging container of the articles.
Abstract: The invention relates to a sheet-type chlorine dioxide gas generant, which comprises a ventilation bag The invention is characterized in that: the bag is also provided with an A sheet absorbing a mixture of sodium chlorate or potassium chlorate, glycerol and water and a B sheet absorbing a mixture of citric acid or tartaric acid and water When the sheet-type chlorine dioxide gas generant is in use, the A and B sheets are overlaid together in the ventilation bag, then the ventilation bag is adhered into the packaging container of the articles to be refreshed, and the chlorine dioxide gas generated in the bag permeates and dissipates outside the bag to form a refreshing gas protection circle around the fruits and vegetables to be refreshed to achieve the effects of preventing corrosion and refreshing
