Decolorization and removal of textile and non-textile dyes from polluted wastewater and dyeing effluent by using potato (Solanum tuberosum) soluble and immobilized polyphenol oxidase
Abstract
Celite bound potato polyphenol oxidase preparation was employed for the treatment of wastewater/dye effluent contaminated with reactive textile and non-textile dyes, Reactive Blue 4 and Reactive Orange 86. The maximum decolorization was found at pH 3.0 and 4.0 in case of Reactive Blue 4 and Reactive Orange 86, respectively. Immobilized potato polyphenol oxidase was significantly more effective in decolorizing the individual dye and complex mixtures of dyes as compared to soluble enzyme. The absorption spectra of the treated and untreated dye mixture and dyeing effluent exhibited a marked difference in the absorption value at various wavelengths. The polluted water contaminated with an individual dye or mixtures of dyes treated with soluble and immobilized potato polyphenol oxidase resulted in the remarkable loss in total organic carbon.

Some examples include increased performance of the immobilised enzyme compared to free (7 % higher performance was noted when polyphenol oxidase was immobilised).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
