為什么文獻(xiàn)中使用pc膜過濾后,濾膜的有效過濾面積為之前的1/10?
|
|
Ultrathin freestanding nanoporous membranes prepared from polystyrene nanoparticles:The filtration area of our filter holder is 2.84cm2 and the porosity of the PC membrane is 10%. Then, the effective surface area is 0.284 cm2.以及 Ultrathin Free-Standing Bombyx mori Silk Nanofibril Membranes:The filtration area of our filter holder is 9.62 cm2 and the porosity of the PC membrane is 10%. Then, the effective surfacearea in our case is 0.962 cm2 實(shí)驗(yàn)部分的計(jì)算都是這樣計(jì)算的。 膜的有效面積不是過濾面積嗎?和孔隙率有關(guān)嗎? |
