Biosorption, isotherm and kinetic properties of common textile dye by phormidium animale
In this study, the potential textile dye biosorption capacity of a
low-cost biosorbent (P. animale) was tested as functions of pH,
biosorbent type, initial dye concentration, temperature, contact time
and biosorbent dosage at batch scale level. The optimal conditions are
2, dried biosorbent, 93.16 mg/L, 45 degrees C, 1440 minutes and 4 g/L
for pH, biosorbent type, initial dye concentration, temperature, contact
time and adsorbent dosage, respectively. Dried P. animale removed 99.66
\% of Remazol Black B (RBB). The isotherm and kinetic models were
analyzed for biosorption mechanism and characteristic. According to the
results, Langmuir isotherm and pseudo second order kinetic models were
compatible with the experimental data obtained for RBB biosorption on
algal biosorbent. Also FTIR and elemental analysis were done and
resulted that the functional groups on the surface of algae had
significant role in biosorption process. The results of this study
supported that P. animale is an effective, inexpensive and eco-friendly
biosorbent for treatment of textile dye wastewater
