formaciones vegetales, así como la endemicidad y grado de amenaza de las especies registradas. Se realizaron colectas botánicas intensivas en las formaciones vegetales y en diferentes pisos altitudinales, a través de transectos y en distintas direcciones, teniendo como punto de partida la ciudad de Ayacucho. Se determinaron 864 especies pertenecientes a 454 géneros y 108 familias entre árboles, arbustos y herbáceas. 91 familias, 371 géneros y 705 especies de la Clase Magnoliopsida y 17 familias con 83 géneros y 159 especies de la Clase Liliopsida. Las familias mejor representadas, Asteraceae 155 especies, seguido de Poaceae 98 y Papilionaceae con 44. Los géneros más dominantes fueron Senecio con 23 especies, Calceolaria 15, Baccharis 14, Solanum 12, Plantago 9, Lupinus, Peperomia y Urtica 8 especies cada uno. El 60% fueron herbáceas, seguida de arbóreas 13% y arbustivas 11% y las demás en menor porcentaje. Las formaciones vegetales que existen en la zona de estudio son los Tunales, Algarrobales, Monte ribereño, Titankales, Quiñuales, Bofedales, Césped de puna y Comunidades mixtas. La distribución es 30% en la parte baja, 28% parte media y 27% en la parte alta. Solamente el 2% de presenta amplia distribución en los tres sectores, mientras en 2 sectores: Baja -Media 5% y Media -Alta 8%. 48 especies amenazadas comprendidas en 42 Géneros y 33 Familias. En Peligro Crítico 9 especies, En Peligro 8, Vulnerable 17. Además, se registró 20 especies endémicas, la Familia Asteraceae y Cactaceae con 6 especies, seguido de Berberidaceae 4, las demás con 2 y 1 especie respectivamente.

“…Both the phosphate removal efficiency (%) and phosphate adsorption capacity (mg g −1 ) were significantly different (p < 0.05) during the different contact times studied (1,6,12,24,36,72, and 168 h). Figure 4 represents the adsorption kinetics of phosphates for S02.…”

Sanky (Corryocactus brevistylus) Peel as Low-Cost Adsorbent for Removal of Phosphate from Aqueous Solutions

et al. 2021

This study aimed to evaluate the adsorption capacity of an adsorbent obtained using sanky peel for the removal of phosphate from aqueous solutions. The study was conducted in two stages: (1) adsorbent preparation considering yield, phosphate removal, adsorption capacity, and textural characteristics; (2) an assessment of the effectiveness of using sanky peel as an adsorbent for removing phosphates from aqueous solutions. Batch adsorption was studied in aqueous solutions containing phosphate and calcium ions with the selected adsorbent. Adsorption kinetics and equilibrium isotherms were studied using mathematical models. The adsorption kinetics followed the pseudo-second-order, Elovich, and Weber–Morris models, thus demonstrating that adsorption rates were not controlled by multiple processes. Adsorption equilibrium data fitted best with the Dubinin–Radushkevich model. Finally, a Fourier transform infrared spectroscopy analysis revealed the presence of brushite spectra bands after adsorption. The results of this study can help better understand the use of sanky peel as an adsorbent and good alternative for aqueous phosphate adsorption.

“…Even though [119] obtained excellent results using Cumulopuntia unguispina on the removal of Cd and Mn from water (Table 3), this cactus is a species that exists only in southern Peru [258], limiting its sustainable extrapolation for water treatment in other regions. However, the species is commonly used for local production in agroforestry systems (marmalades, nectars, alcoholic beverages, shampoo, slope stabilization, etc.…”

There is interest in using locally available, low cost organic materials to attenuate heavy metals such as Cd, Cr, Cu, Hg, Ni, Pb, and Zn found in surface waters in Peru and other developing regions. Here we mesh Spanish language publications, archived theses, and prior globally available literature to provide a tabulated synthesis of organic materials that hold promise for this application in the developing world. In total, nearly 200 materials were grouped into source categories such as algae and seashells, bacteria and fungi, terrestrial plant-derived materials, and other agricultural and processing materials. This curation was complemented by an assessment of removal potential that can serve as a resource for future studies. We also identified a subset of Peruvian materials that hold particular promise for further investigation, including seashell-based mixed media, fungal blends, lignocellulose-based substrates including sawdust, corn and rice husks, and food residuals including peels from potatoes and avocadoes. Many studies reported percent removal and/or lacked consistent protocols for solid to liquid ratios and defined aqueous concentrations, which limits direct application. However, they hold value as an initial screening methodology informed by local knowledge and insights that could enable adoption for agriculture and other non-potable water reuse applications. While underlying removal mechanisms were presumed to rely on sorptive processes, this should be confirmed in promising materials with subsequent experimentation to quantify active sites and capacities by generating sorption isotherms with a focus on environmental conditions and specific contaminated water properties (pH, temperature, ionic strength, etc.). These organics also hold promise for the pairing of sorption to indirect microbial respiratory processes such as biogenic sulfide complexation. Conversely, there is a need to quantify unwanted contaminant release that could include soluble organic matter and nutrients. In addition to local availability and treatment efficacy, social, technical, economic, and environmental applicability of those materials for large-scale application must be considered to further refine material selection.
