        Summary
        In this thesis the diffusion of salt through porous carbon is studied. In particular, we use the colloidal charge sensor setup [1, 2] to determine the diffusion rate of salt through an externally charged porous carbon membrane. We succeeded in performing these measurements, but we had to use a few workarounds for practical problems. Salt transport across the membrane appeared to occur mainly via wide pores in which ions are hardly affected by changes in surface charge. [1] Albert P. Philipse, Bonny W. M.
