摘要: 本文通过对黄豆和黑芸豆蛋白的甲基化与去酰胺化的改性处理，研究了黄豆和黑芸豆蛋白官能团改性后对高岭土悬浮液和淀粉废水的絮凝作用。研究表明，甲基化改性黄豆蛋白可使高岭土悬浮液透光率下降11.99%，而甲基化改性黑芸豆蛋白则使高岭土悬浮液透光率上升3.28%；去酰胺化改性的这两种蛋白可使高岭土悬浮液透光率上升28.74%和18.53%。甲基化改性黄豆和黑芸豆蛋白可使淀粉废水透光率上升9.35%和2.18%；去酰胺化改性的这两种蛋白可使淀粉废水透光率上升21.19%和18.73%。去酰胺化改性黄豆和黑芸豆蛋白絮凝效果优于甲基化改性黄豆和黑芸豆蛋白絮凝效果。
Abstract: In this paper, the flocculation of kaolin suspension and starch wastewater with modified functional groups of soybean and black kidney bean protein was studied by methylation and deamidation of soybean and black kidney bean protein. The results showed that the light transmittance of kaolin suspension was decreased by 11.99% by methylation of soybean protein, increased by 3.28% by methylation of black kidney bean protein, and increased by 28.74% and 18.53% by deamidation of the two proteins. The light transmittance of starch wastewater increased by 9.35% and 2.18% by methylation modified soybean and black kidney bean protein, and 21.19% and 18.73% by deamidation modified soybean and black kidney bean protein. The flocculation effect of deamidated soybean and black kidney bean protein was better than that of methylated soybean and black kidney bean protein.
