The application of sodium citrate in Co_3O_4 nano-particle dispersing system

摘要

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: l0min, 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 Co_3O_4 nano particle was measured with Malvern Nano Zetasizer to be 217nm.
