Acquisition of Hydration States of Zinc Acetate Dihydrate and Aluminium Potassium Sulfate Dodecahydrate by Microwave Sensor

摘要：

A novel microwave sensor was developed to acquire the information of various hydration states of salt hydrates, which is a key parameter in chemistry, metallurgy, mineralogy and geology. Various hydration states of zinc acetate dihydrate (Zn(CH3COO)3·xH2O; x=2) and aluminium potassium sulfate dodecahydrate (KAl(SO4)2·xH2O; x=12, 6) were detected by the microwave sensor, respectively. It was found that the results obtained by the sensor were in good agreement with those determined by TG and DTA. Besides the kinetics can be detected real-timely, the microwave absorption properties during losing crystalline water of Zn(CH3COO)3·2H2O and KAl(SO4)2·12H2O could also be detected by the microwave sensor.
