The ability of polyamide 6 nanofibers membrane (P6NM) to remove acid dyes from effluent solution by adsorption has been studied. Equilibrium isotherms for the adsorption of three acid dyes, Acid blue 41 (AB41), Acid blue 78 (AB78), and Acid yellow 42 (AY42), on P6NM were measured experimentally. Simulated wastewater of acid dyes with the concentration of 10 mg/L for sorption process electrospun polyamide 6 with mass per unit area 12 g/m2 was used as the sorbent material. Ten sets of P6NM were dipped in separate simulated effluent. The weight of the original P6NM and the concentration of left solution were detected. Results were analyzed by the Langmuir equation using a linearized correlation coefficient. And it showed that all the dyes tested could follow the Langmuir adsorption isotherm, which gave excellent correlation for all the dyes.
