Abstract
The influence of pH on reactive dyes adsorption from solution
is studied in this paper. The adsorbent used was flltrasorb 400
(FS-400) which showed a high equilibrium capacity for hardly
adsorbable reactive dyes. The adsorption performance of FS-400
was not affected over a wide pH range (3-10), hence FS-400 is
considered as a pH-insensitive adsorbent. Hydrolysed reactive dyes,
the state at which reactive dyes are usually discharged, were effectively
adsorbed by FS-400. Capacities ranging from 20-80% by
weight of FS-400 have been realized.
