A B S T R C TEfforts to substitute synthetic dyes on fabrics for natural are currently increasing. Research and innovation extremely needed support those attempts so that the quality of is more competitive than dyes. This study aims optimize dyeing parameters cotton using dye extracts derived from barks Tegeran (Cudrania javanensis), Merbau (Intsia bijuga), Tingi (Ceriops tagal), Jambal (Peltop...

The ability of two varieties (hard and soft) of almond peels, as inexpensive sorbents for the removal of bezanyl red (acid dye) from synthetic aqueous solutions has been studied. After their characterization by different techniques, (elemental analysis, biochemical analysis, IR spectroscopy, thermogravimetric analysis, scanning electron microscopy and mercury porosimetry), the dye sorption kine...

Discharges of highly colored dye effluents in natural water constitute a significant burden on the environment. The solar driven photo-Fenton process based on Fe(III)-oxalate complexes, an important advanced oxidation processes (AOP) technology, has been attracting growing attention for the decomposition of organic dyes. Such processes are based on the light enhanced generation of the highly re...

Lawsone a natural pigment present in the henna leaves has been used as a skin and hair dye since 1400 BC. The concentration of this natural compound in leaves varies from place to place depending upon many of the environmental factors and the highest quantity reported so far is about 1% of the dry mass. Heretofore, it has been reported that natural colored extracts and isolate from Henna leaves...

Blue dye (indigo) from Indigofera tinctoria leaves is a popular natural used worldwide. The lower light fastness of indigo dyes compared to that synthetic blue one the drawbacks former, limiting its utiliz
