“…The absorption bands between 1750 and 1735 cm −1 correspond to C = O stretching vibration of methyl esterified groups (Kpodo et al, 2017) and the regions of 1650-1600 cm −1 are related with the carboxyl group (COOH) (Kpodo et al, 2017;Nejatzadeh-Barandozi & Enferadi, 2012) meanwhile, Synytsya, Čopíková, Matějka., and Machovic (2003) reported the stretching vibrations of carboxylate anion (COO − ) at 1633 cm −1 . The band at 1320 cm −1 is assigned to C-H methyl vibration of the rhamnose ring commonly present in the mucilage obtained from Opuntia spp (Vargas-Rodríguez et al, 2016). The bands at 1300 and 1050 cm −1 indicate the presence of carbohydrate units, corroborated by the galactose absorption band at 778 cm −1 , it is in conformity with the monosaccharide composition of this fraction.…”

“…El color (tono o matiz) de la sopa con almidón comercial como espesante y las que contenían mucílago fue amarillo; y el tono de los mucílagos aislados se identificó en el espacio amarillo-verde. Este fue parcialmente diferente al color mostaza documentado en el mucílago aislado de cladodios de O. ficus-indica por Vargas-Rodríguez et al (2016). El ángulo de tono de la sopa espesada con almidón fue de 79.5º, independientemente de la concentración de almidón espesante; seis de los diez tratamientos con mucílago no mostraron diferencias significativas en el matiz respecto a su testigo.…”

“…In this regard, some studies have reported the usefulness of prickly pear cactus cladode extracts as flocculants during water clarification, and as adsorbents of metals in contaminated waters [19,20]. Its adsorption mechanism is related to the presence of polymers in the cladode mucilage, whose main components are arabinose, galactose, rhamnose, xylose, galacturonic acid, and specially, pectin [21]. However, as in other cases, the main disadvantage of this alternative is the high cost involved in obtaining and purifying the extracts, which contain high concentrations of polymers, in particular, pectin [18,19].…”

“…This indicates that 2 hours of treatment is enough to reduce the metallic content, since the adsorbent reaches its maximum adsorption capacity due to the saturation of the pectin -COOH groups. The latter act as chelating agents for metal ions [17,21,23,24], leading to the equilibrium of the adsorbent-adsorbate system [25], i.e, from that moment on the adsorbent is no longer able to adsorb more metal ions.…”
