Embodiment 1
[0058] Step 1: Under the pressure of the syringe pump 9, through the liquid inlet pipe 8, the pretreated natural seawater flows in from the inlet channel in the microfluidic chip 7 at a flow rate of 20ul / min, and at the same time, microfluidic water is injected into the buffer solution. Channel 77 is injected with buffer solution (borate). The size of microfluidic chip 7 is 20mm×20mm. The water inlet microchannel 73 of the chip, the concentrated seawater outlet microchannel 74 and the fresh water outlet microchannel 76 are Y-shaped. The width of the water microchannel 73 is 500um, the width of the concentrated seawater outlet microchannel 74 and the freshwater outlet microchannel 76 is 250um, and the concentrated seawater outlet microchannel 74 and the freshwater outlet microchannel 76 form 30°, the buffer solution microchannel 77 of the chip In an inverted V shape, the width of the buffer solution microchannel 77 is 500um, and the thickness of each microchannel is 100um, while...
