Carboxymethyl inulin (CMI) has been synthesized by incorporation of carboxymethyl groups in the inulin framework; by reacting inulin with sodium salt of monochloro acetic acid (SMCA) in presence of sodium hydroxide. The resulting carboxymethylated product, with different degrees of substitution, has been confirmed through various physicochemical characterization techniques, such as intrinsic viscosity measurement, elemental analysis (C, H, N and O), FTIR spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) studies. Flocculation efficacy of various grades of CMI, have been studied in kaolin suspension and then in municipal wastewater, in relation to inulin (parent polysaccharide). This has been done utilizing jar-test procedure towards possible application as a flocculant for waste water treatment.
羧甲基菊粉（CMI）是通过在菊粉骨架中引入羧甲基基团而合成的；在氢氧化钠存在下，使菊粉与一氯乙酸的钠盐（SMCA）反应。通过各种物理化学特性鉴定技术，如特性粘度测量、元素分析（C、H、N 和 O）、傅里叶变换红外光谱（FTIR）、热重分析（TGA）和扫描电子显微镜（SEM）研究，证实了具有不同取代度的所得羧甲基化产物。研究了不同等级的 CMI 在高岭土悬浮液中的絮凝效果，然后在城市废水中，与菊粉（母体多糖）进行了对比。这是通过使用搅拌试验程序来实现的，目的是将其作为废水处理的絮凝剂进行应用。
