摘要
Using black wattle tannin and paraformaldehyde in fluid-wax as organic dispersant,a spherical tannin-chelated resin was prepared through inverse-suspension polymerization.The condition of reaction was determined by means of orthognonal experiment.The optimal condition of synthesis was:m(tannins)∶m(paraformaldehyde)12∶1,reaction temperature 67 ℃,reaction time 3.5 h,fluid-wax volume 65 mL.The structure of the product was characterized by Fourier transform IR,XRD,TG,DSC and SEM.The adsorption mechanism of tannin-chelated resin toward Cr6+ was investigated.
