纳米铁酸锌的分散

Dispersion of Nano-zinc Ferrite

研究了阴离子型、阳离子型和非离子型的表面活性剂对纳米铁酸锌在水中分散的稳定性的影响,探讨了不同种类分散剂用量、纳米铁酸锌浓度、超声波分散时间及pH对纳米铁酸锌水分散体系的影响。结果表明,最佳分散剂为十二烷基苯磺酸钠和十二烷基硫酸钠,最佳分散工艺条件为:分散剂用量为0.3%,pH为3～5,超声波分散时间为15 min。

Studied on the dispersion of nano-ZnFe2O4 powder in water by different dispersing agents,the influence of different dispersants dosage,pH of nano-ZnFe2O4 dosage on the nano-ZnFe2O4 dispersion system.The result showed that the optimal dispersant sodium dodecylbenzene sulfonate（SDBS） and sodium dodecyl sulfate（SDS）concentration was 0.3 %,pH dosage was 3～5,ultrasonic irradiation time 15 min.
