1. using carboxymethyl manioc waste as the method for Material synthesis high hydroscopic resin, it is characterised by, its method and step are:

  • (1) carboxymethyl manioc waste and deionized water are pressed 1;

    8 mass ratio mixing;

    Weigh 4 ~ 12 times of carboxymethyl manioc waste qualityAcrylic acid, the sodium hydroxide of 0.1113 ~ 0.3887 times of acrylic acid quality is weighed, dissolved respectively with 27.5ml deionized water above-mentionedThe sodium hydroxide of scope;

    With in above-mentioned sodium hydroxide solution and acrylic acid under ice-water bath cooling;

    (2) above-mentioned carboxymethyl manioc waste and the mixed liquor of deionized water are existed with the acrylic acid solution neutralized with sodium hydroxide partIt is well mixed in reaction bulb, adds the potassium persulfate solution containing carboxymethyl manioc waste quality 1 ~ 5% and make initiator, addition containsThe N of carboxymethyl manioc waste quality 0.4 ~ 1.2%, N '"'"'-methylene-bisacrylamide solution make crosslinking agent, and stirring is allowed to well mixed,Nitrogen is passed through, being stirred continuously slow heating is stepped up temperature of reaction system, stops stirring when temperature rises to 70 ~ 80 DEG C,Continue heating and be incubated 2h when temperature reaches 90 DEG C after, taking-up product, drying, crush and produce high hydroscopic resin.
