Preparation of Sulfuric Acid Sulfonated Modified Starch and Testing Study of Its Scale Inhibition Properties
摘要
Abstract
In order to mitigate and avoid current scale inhibitor pollution emissions on the environment, in this lab, the concentrated sulfuric acid oxidized starch is used to prepare the modified starch, whose color is brown-red.Sulfuric acid sulfonated modified starch is tested in case of different concentrations, temperatures, Ca2+ concentrations, pH values.It has been found that the best concentration of efficient scale of sulfuric acid sulfocated modified starch is 0.61 mg/L, and that the best temperature is 80 ℃, and that under this best concentration and temperature the corresponding inhibition rate is 84.7 ％.The inhibition rate of sulfuric acid sulfonated modified starch decreases with an increase in Ca2+ concentration and pH value, thus, indicating that Ca2+ concentration and pH are the important factors that can affect the inhibition rate of scale inhibitor.Finally, the comparison is made of scale performance between sulfuric acid sulfonated modified starch and other oxidized modified starch, with the results showing that the scale inhibition of sulfuric acid sulfonated modified starch is superior to other oxidized modified starch.关键词
