Linearization of the second order kinetic model for CS essential oil isolation using conventional CCH, and Dual-function GC/MS optimized ultrasound-assisted hydrodistillation prototype (DF-GC/MS-HUS) methods.

Isolation methodsa	Slope	Cs (g L−1)	Intercept	K2 (L g min−1)	R2
Conventional CCH	9.94 × 10− ± 0.001	0.020 ± 0.001	− 3.341 × 10–7 ± 0.001	0.0673 ± 0.0001	0.9940 ± 0.0001
