example 1
[0110]This example provides a nano-sulfur containing composition, the raw materials of which comprise sodium thiosulfate pentahydrate, hydroxypropyl starch ether, hydrochloric acid and water. The preparation method was as follows:
[0111]50 g of sodium thiosulfate pentahydrate and 1 g of hydroxypropyl starch ether were weighted, and sodium thiosulfate pentahydrate was dissolved in water to prepare an aqueous sodium thiosulfate solution containing 50% by mass of sodium thiosulfate. Hydroxypropyl starch ether was then added to the aqueous sodium thiosulfate solution, and finally a 10% by mass hydrochloric acid solution was added to the aqueous sodium thiosulfate solution (wherein the molar ratio of the added thiosulfate to the hydrogen ion was 1:2), and the system was ultrasonically stirred until the reaction was completed, to give a nano-sulfur containing composition. The mass content of nano-sulfur in the obtained nano-sulfur containing composition was about 3.06%. The nano-sulfur con...
example 2
[0112]This example provides a nano-sulfur containing composition, the raw materials of which comprise sodium thiosulfate, guar gum, acetic acid, and water. The preparation method was as follows:
[0113]50 g of sodium thiosulfate and 1.5 g of guar gum were weighed, and sodium thiosulfate was dissolved in water to prepare an aqueous sodium thiosulfate solution containing 60% by mass of sodium thiosulfate, and then guar gum was added to the aqueous sodium thiosulfate solution, and finally a 10% by mass acetic acid solution was added to the sodium thiosulfate solution (wherein, the molar ratio of added thiosulfate to hydrogen ion was 1.05:2), and the system was ultrasonically stirred until the reaction was completed, to give a nano-sulfur containing composition. The mass content of nano-sulfur in the obtained nano-sulfur containing composition was about 2.17%. The nano-sulfur containing composition prepared in this example further contained sodium acetate as a by-product, which can be use...
example 3
[0114]This example provides a nano-containing sulfur composition, the raw materials of which comprise sodium thiosulfate, phosphorylated distarch phosphate, acetic acid and water. The preparation method was as follows:
[0115]50 g of sodium thiosulfate and 2 g of phosphorylated di starch phosphate were weighted, and sodium thiosulfate was dissolved in water to prepare an aqueous sodium thiosulfate solution containing 65% by mass of sodium thiosulfate; the phosphorylated disstarch phosphate was added to a 40% by mass acetic acid solution to form a mixed solution, and then the mixed solution was added to the aqueous sodium thiosulfate solution (wherein the molar ratio of the added thiosulfate to the hydrogen ion was 1:2), and the system was ultrasonically stirred until the reaction was completed, to give a nano-sulfur containing composition. The mass content of nano-sulfur in the obtained nano-sulfur containing composition was about 5.9%. The nano-sulfur containing composition prepared ...
