As can be shown, the removal percentage in dyes is quite different depending on the specific pollutant we are dealing with. Froman almost 10% (removal of Quinoline yellow) to a removal efficiency higher than 80% in the case of Amaranth, the differences must be attributed to the specific chemical structure and to the molecular weight, being Amaranth the most removable probably due to its high molecular weight (604 g mol−1)). The reason of the low level of Quinoline Yellow removal can be found in the fact that it presents lower molecular weight but mainly the structure presents shorter carbon chains, it is a more spherical geometry. However, despite the low remediation rates in the case of Methylene Blue and Quinoline yellow, q capacities are quite high: 30, 80, 340 and 410 mg g−1,respectively.
