The role of initial substrate conce

The role of initial substrate concentration, iron oxide nanoparticles concentration and pH on hydrogen production
from distillery wastewater was well investigated in this batch study. Addition of iron oxide nanoparticles has shown
enhancement effect on hydrogen production. The highest cumulative volume of hydrogen (380 ml), hydrogen
content (62.14%) and % COD reduction (72.5) was obtained under the optimal conditions (initial substrate
concentration of 110 g L-1 with nanoparticle concentration of 50 mg L-1 at pH 6).The comprehensive kinetic analysis
of RH2, SHY, Rate of substrate utilization and biomass growth under different operational conditions (initial
substrate concentration, iron oxide nanoparticle concentration and pH) was conducted. Kinetic analysis reveals the
correlation between hydrogen production, substrate utilization and biomass growth. The high correlation coefficient
indicated the suitability of the kinetic models to describe the experimental data satisfactorily
