Answer 2

Answer:

Concept:

The rejection coefficient is a measurement of the volume of a solute that does not pass through a semi-permeable barrier during a separation process. Based on the average pore size and pore size distribution of mineral membranes and under the assumptions of a sieve mechanism for membrane crossflow and negligible adsorption, the rejection coefficient for the ultrafiltration of monodisperse solutes (polystyrene in cyclohexane at theta temperature) was calculated.

Explanation:

• A membrane's rejection coefficient is zero when an aqueous solute readily flows through it.
• The quantity of solute that is left behind on top of the membrane after trying to pass through it is analysed to determine the rejection coefficient, in essence.
• The rejection coefficient is 0 because the dissolved substance readily traversed the membrane and there was no dissolved substance remaining on top of the membrane.
