The Application of Sodium Citrate in Co₃O₄ Nano-Particle Dispersing System

Abstract:

Based on the profound application, the Co₃O₄ was chosen to be research object; the optimized dispersing condition was studied and determined as: dosage of Co₃O₄ nano particle varied from 0.01 to 0.02mg/ml, sodium citrate was determined to be dispersing adjuvant with a dosage of 0.0005g/ml, ultrasonic time: 10min, and pH value was 7 to 8 when the Zeta potential was –57.1mv. After a detailed discussion of size distribution and dispersing condition, the size distribution of Co₃O₄ nano particle was measured with Malvern Nano Zetasizer to be 217nm.
