摘要：为了开发新型生物基聚磷腈吸附材料,以六氯环三磷腈(HCCP)、染料木素(GEN)、4,4′-二羟基二苯二硫醚(HPS)为原料,采用超声辅助一步沉淀聚合法合成了环交联聚磷腈(HGES)。红外光谱(FTIR)、X射线衍射(XRD)证明HCCP中的—Cl基团与GEN、HPS中的—OH基团发生亲核取代反应,形成无定型HGES。扫描电子显微镜(SEM)表明HGES为平均粒径约为254 nm的球形颗粒;动态光散射(DLS)测试表明其表面平均Zeta电位为-286 mV。研究结果表明,HGES可有效吸附水中阳离子染料,对亚甲基蓝(MB)的去除率在30 min内达到100%,吸附动力学符合准二级模型,吸附等温线符合D-R模型,饱和吸附量为52.64 mg·g^(-1)。
A bio?based polyphosphazene adsorption material abbreviated as HGES was synthesized by ultrasonic?as?sisted one?step precipitation polymerization of hexachlorocyclotriphosphonitrile(HCCP),genigenitin(GEN)and 4,4′?dihydroxydiphenyl disulfide(HPS).Fourier transform infrared spectrometer(FTIR)and X?ray diffraction(XRD)spectra demonstrated that nucleophilic substitution reaction occurred between—Cl of HCCP and—OH of GEN and HPS,and the synthesized HGES was amorphous.Scanning electron microscope(SEM)images showed that HGES particles were spherical and have an average particle size of about 254 nm.The average Zeta po?tential of HGES measured by dynamic light scattering(DLS)was-286 mV.Research results show that HGES can effectively adsorb cationic dyes in water.The removal rate of MB by HGES can reach 100%within 30 min.The ad?sorption kinetics of HGES to methylene blue is consistent with the quasi?second?order model,the adsorption iso?therm is consistent with the D?R model,and the saturated adsorption capacity is 5264 mg·g-1.
