| Abstract: | Recently the research of starch has been got more attention in leather-making,because the starch is a regeneration source.The experiment synthesized a oxidized starch with carboxyl and aldehyde groups by H_2O_2 and sodium periodate.The physical and chemical properties and structure were analyzed,including the determination of dry content,pH,carboxyl and aldehyde groups.Through infrared and gel spectrum,the structure of oxidized starch was explained.It's convenient to application in leather-making. |
