Abstract

Treatment of mono-azo dye, tectilon yellow 2G (TY2G), by Chlorella vulgaris was investigated. COD removal efficiencies were determined as 69, 66 and 63% for the initial TY2G concentrations of 50, 200 and 400 mg/l, respectively, whereas acclimation of C. vulgaris caused them to increase to 88, 87 and 88%, respectively. Absorbance spectral profiles obtained for unacclimated algae showed that the peak observed initially at 450 nm disappeared and the one at 220 nm decreased remarkably while there was a new peak formation at 350 nm, indicating the conversion of TY2G to an end product which was further confirmed as aniline by high-performance liquid chromatographic analysis. In the case of acclimated algae, no aniline production was detected. The main mechanism of the removal was bioconversion in the case of unacclimated algae and degradation in the case of acclimated algae. Moreover, the higher the initial algal concentration, the higher is the COD removal efficiency achieved in a much shorter time.

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.
