| dc.description.abstract1 | The cyanotoxin cylindrospermopsin (CYN) has become a significant environmental and
human health concern due to its high toxicological potential and widespread distribution. High
concentrations of cyanotoxins may be produced during cyanobacterial blooms. Special attention
is required when these blooms occur in sources of water intended for human consumption since
extracellular cyanotoxins are not effectively removed by conventional water treatments, leading
to the need for advanced water treatment technologies such as the Fenton process to produce safe
water. Thus, the present study aimed to investigate the application of the Fenton process for the
degradation of CYN at bench-scale. The oxidation of CYN was evaluated by Fenton reaction at
H2O2/Fe(II) molar ratio in a range of 0.4 to 4.0, with the highest degradation of about 81% at molar
ratio of 0.4. Doubling the concentrations of reactants for the optimized H2O2/Fe(II) molar ratio, the
CYN degradation efficiency reached 91%. Under the conditions studied, CYN degradation by the
Fenton process followed a pseudo-first-order kinetic model with an apparent constant rate ranging
from 0.813 × 10−3
to 1.879 × 10−3
