Magnetic Solid-Phase Extraction Based on β-Cyclodextrins/Acrylic Acid Modified Magnetic Gelatin for Determination of Moxidectin in Milk Samples

Table 1

Comparison of the sample preparation procedures between different methods.

Matrix	Clean-up method	Volume (mL)	LODs (ng⋅mL^−1)	Reference
Bovine tissue	C18 SPE	16 + 8	0.1	[1]
Bovine muscle	Freeze-drying for 12 h	—	0.1	[3]
Animal liver	Alumina-N SPE	45 + 18	0.8	[8]
Milk	C18 SPE and carbon SPE	100 + 33	5	[9]
Milk	MSPE		0.1	This work

The volume consists of loading volume and washing/eluting volume. Because of magnetic separation and high efficiency, extraction of MOX could reach equilibrium not more than 3 min.
