Hello every body: its Bashir over here.

I really have very serious question need to be solved as soon as possible, I have tried but could not reach the right answer , so please everyone of you who has an ability to sort it out please do it.

Note: You can use any assumptions if u need.

The question is:

I have a solution of humic acid ( 10mg/l) into 100ml glass pottle ( volume ) and that means my solution is 100ml

I have put an adsorbent ( materila ) to adsorb humic acid from the solution which is deionized water.
My adsrobent material is polymer beads ( cylindrical shape ) have a very low surface area about 1.0 m2/gm.

if you know that Avogadro number is 6.022 * 10 *^23 and the humic acid molecule diameter ( size ) is around 1.5nm.

And we assume that the humic acid will be adsorbed as a monolayer not multilayer.

The weight of each bead is about 0.044gm

You can assume or calculate if u need how much beads should i put in the solution to adsorb a specific amount of humic acid.


Finally : by these informations could u know how much mgs of humic acid will be adsorbed on these beads as a monolayer

Please try to answer if there is anything missing if is very necessary to solve this problem so you can assume it.

Regards

Bashir

It looks like a "lazy student question". What's exactly the problem you are facing?
