Removal of reactive dye using novel low cost activated carbon obtained from <em>Prunus</em> × <em>yedoensis</em> leaf by chemical activation

Abstract

The eco-friendly production of activated carbon from <em>Prunus</em>×<em>yedoensis</em> tree leaf (PYTL) for the removal of Remazol brilliant violet-5R reactive (RBV) dye has been studied for the first time. This carbon has been obtained by the chemical carbonization using concentrated H₂SO₄in a ratio of 2:1 (H₂SO₄: PYTL, v/w) followed by drying at 150ºC for 24 hr. The RBV treated and untreated carbon is characterized using HR-FESEM, EDS, XRD, FTIR, and BET analysis. The PYTL carbon is found to be 100 mg/L, maximum removal of 10 ppm, in the time frame 60 min and the desorption 20 mg/L.
