A novel cationic natural organic polymeric flocculant DXSL-I was prepared using corn-core-powder(QCCP, <0.147 mm) as matrix and triethylamino-epoxypropane(TAEP prepared from triethylamine and epichlorohydrin) as cationic reagent. The reaction was initiated by H_2O_2-FeSO_4. The preparation conditions were optimized as follows:2.0 g QCCP was at first alkalified with 0.6 g NaOH in 8 mL H_2O( 0.1%(mass fraction) NaCl as depressor) at 40 ℃ in 60 min, then etherified with 8 mL TAEP at 55 ℃ for 3.5 h in the...

The present paper introduces the authors' method on preparing a new cationic natural organic polymeric flocculant DXSL-Ⅰ, known as a kind of green colored environment-protecting flocculant. The polymeric flocculant can be obtained by using quasi-corn-core-powder (QCCP, φ < 0.147 mm) as matrix and triethylamino-epoxypropane (short for TAEP) as cationic reagent in a reaction triggered by H_2O_2-FeSO_4. The preparing conditions have been optimized through a series of orthogonal experiments. First of all, 2.0 g QCCP was alkalified with 0.7 g NaOH in 8 mL H_2O ( 0.1ωA)% NaCl as depressor ) at 40 ℃ for 60 min, then etherified with 8 mL TAEP at 55 ℃ for 3.5 h, co-existing with ω (H_2O_2-FeSO_4) 0.01%. The performance evaluation can be carried out by adding drops of flocculant to a turbid solution prepared by stirring 2 g Gaolin powder in 200 mL water. Five minutes later, the transparency of the solution in the midst were quickly to get to 95%, which indicates that its performance could be as good as that of polyacrylamide, a widely used flocculant. In addition, the authors have also analyzed QCCP, alkalized QCCP and DXSL-Ⅰfor their chemical structure and micro-forms through IR and SEM. On the whole, it can be concluded that DXSL-I, as a kind of low-priced and an easily-prepared raw material, is expected to be a promising chemical material with broad prospect of practical use in water treatment.
