Table 2. Mass Balance of MB Dye in the Feed, Permeate, and Concentrate for DG-CSGO Membranes.

pressure (psi)	feed (mg MB)	permeate (mg MB)	concentrate (mg MB)	MB loss (mg)
20	66.8449	0.0017	65.8359	1.0072
50	63.7151	0.0018	64.5282	0^a
110	61.4986	0.0035	61.9195	0^a

Concentrate stream contained greater mass of MB than feed, which indicates an analytical error and no observable adsorption.
