Abstract

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)₃ldrxH₂O; x=2) and aluminium potassium sulfate dodecahydrate (KAl(SO₄)₂ldrxH₂O; 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)₃ldr2H₂O and KAl(SO₄)₂ldr12H₂O could also be detected by the microwave sensor.
