To what material is the membrane permeable
WebThe overall process, i.e. the flux of permeant (Q) is proportional to the membrane are A, the potential difference (Δφ) between the two sides of the membrane, and inversely proportional to the thickness of the membrane (L): Q = dm/dt = P · A · Δφ / L. or in th case of a gas with Δp the (partial) pressure difference: Q = dm/dt = P · Δp ... WebThis dual-mechanism-driven PC-GOF membrane exhibits superior metal ion rejection, anti-fouling ability, good operational stability, and ultra-high permeance (five times that of pristine GO membranes), enabling a sound step towards a sustainable water–energy–food nexus.

WebMedium. Solution. Verified by Toppr. Correct option is C) Selectively / differentially permeable membranes are the membranes, which allow some substances to pass through them more readily than others. All living biological membranes are selectively permeable. So, the correct answer is 'allows only certain materials to pass through'.
