Abstract: The objective of the present study was to compare between the mixed dyeing of wool fiber in one and two dye baths using natural indigo (Indigofera tinctoria) and madder colorants (Rubia tinctorum). Based on the reduction and oxidation reaction conditions under the same dyeing mechanism for the indigo and madder colorants, the exhaustion rate of the... Show More

Abstract: The aim of this study was to investigate the photodegradation of organic pollutants in natural environment with co-existence of iron oxides and oxalic acid. Methylene Blue (MB) was selected as a model pollutant while Fe₂O₃ was selected as iron oxide. Commercial Fe₂O₃ was calcined at 300°C, 400°C and 500°C and was used to degrade MB in oxalate solut...
