The flow/pumping rate of oils with different viscosities (simplified as ‘vis’) vs time based on the apparatus assembled with the USTC-6@GO@sponge sorbent, a self-priming pump and tubes: (left) the voltage for Mini Electric Motor 360 S and the inner diameter of the tube are 4 V and 1.5 mm (outer: 2 mm), respectively. (Right) The voltage for the diaphragm pump R385 and the inner diameter of the tube are 12 V and 3.5 mm (outer: 5 mm), respectively.
