dc.description.abstract | The world is facing with global water crisis because around 20 % of untreated or partially
treated wastewater is discharged directly into the environment. The main objective of this paper
was to develop an eco-friendly, sustainable biocatalyst for the decolorization of wastewater from
different industries colored with anthraquinonic dyes. Anthraquinonic dyes have fused aromatic
rings, which makes them extremely stabile against photolytic degradation as well as microbial
attack. They are synthesized from antracene, toluene, benzidine so their brakedown products are
toxic, muthagenic, carcinogenic. Natural clay, kaolin was used as a support for the
immobilization of horseradish peroxidase. Prior to immobilization kaolin was activated with
different concentrations of glutaraldehyde (0.1-1%). Next, concentration of the enzyme was
varied in the range 0.5-5 mg cm-3
, and the maximum loading of 2.19 mg g-1 was obtained. The
efficiency of the attained biocatalyst was examined in the reaction with model dye C. I. Acid
Violet 109. Under defined conditions more than 90 % of the dye was removed within 40 min.
Immobilized HRP approved as a much more stable in a wider pH range than free HRP. Besides,
inhibitory influence of peroxide and dye after immobilization was reduced significantly.
Furthermore, immobilized HRP exhibited reasonable reusability during the decolorization of
tested anthraquinonic dye. | sr |
