“…For glyphosate sorption, K d values were on average 116 L kg -1 in CL-CaCO 3 and 703 L kg -1 SCL-Fe 2 O 3 with CaCl 2 , and on average 117 L kg -1 in CL-CaCO 3 and 632 L kg -1 SCL-Fe 2 O 3 with KCl. In calcareous soils, Ca 2+ in forms a bridge between negatively charged soil colloids and glyphosate molecules in soil (Zhao et al, 2015) and, because of the already high free calcium content in the CL-CaCO 3 soil, the addition of Ca with 0.01M CaCl 2 solution had no impact on glyphosate sorption. For the SCL-Fe 2 O 3 soil, glyphosate sorption was greater with 0.01M CaCl 2 than 0.01M KCl, suggesting that glyphosate was able to form complexes with Ca 2+ in solution for enhanced sorption (Glass, 1987).…”

Phosphate and glyphosate molecules compete for sorption sites in soil. The objective of this study was to quantify the impact of Olsen P concentrations in two contrasting soils on phosphate and glyphosate sorption. Soils were a sandy clay loam soil rich in iron oxides (SCL-Fe 2 O 3) and a clay loam soil rich in calcium carbonates (CL-CaCO 3). The phosphate Freundlich sorption coefficient (K f) ranged from 3 to 68 L 1/n mg 1-1/n kg-1 in the SCL-Fe 2 O 3 and from 21 to 76 L 1/n mg 1-1/n kg-1 in the CL-CaCO 3. Glyphosate sorption coefficient (K d) ranged from 293 to 1173 L kg-1 in the SCL-Fe 2 O 3 but only 99 to 141 L kg-1 in the CL-CaCO 3. Glyphosate K d and phosphate K f values decreased significantly with increasing Olsen P concentrations in both soils. Glyphosate K d values were further significantly reduced when phosphate was added to the slurry solutions, but phosphate K f values were not impacted by the presence of glyphosate in solutions. We conclude that annual phosphate fertilizer applications leave phosphate concentrations in Prairie soils to the extent that soils have a lesser capacity to retain glyphosate and phosphate that are subsequently applied, but glyphosate residues will not influence phosphate sorption.

“…En las 20 muestras colectadas en noviembre de 2013 se detectó la presencia de glifosato (Tabla 3). De acuerdo a la bibliografía (Hagner, et al, 2015;Lupi, et al, 2015;Zhao, et al, 2009Zhao, et al, , 2015De Miranda, et al, 2011), este herbicida está considerado como poco móvil y de bajo potencial de lixiviación a través de los suelos hacia las aguas subterráneas. Los resultados obtenidos indican que a pesar de ello es capaz de alcanzar los cuerpos de agua por escorrentía, lo que concuerda con los trabajos de Imfeld et al (2013).…”

En el entorno de la Laguna de Rocha se ha visto incrementada la superficie dedicada a las actividades agrícolas con un mayor uso de plaguicidas, entre ellos el herbicida glifosato, usado en cultivos de soja principalmente. Mediante la utilización de técnicas de inmunoensayo enzimático (ELISA), se investigó la presencia de glifosato en la Laguna y algunos de sus afluentes en dos momentos específicos de tiempo. Se detectó glifosato en 27 de las 28 muestras estudiadas. Muestras positivas por ELISA fueron confirmadas por cromatografía iónica. El método ELISA demostró ser una herramienta de screening adecuada para determinar la presencia de glifosato en agua.

“…This condition indicates that the adsorption reaction of RM on Pb 2+ is chemical adsorption, and the adsorption process requires an activation energy. Therefore, the adsorption rate can be improved by increasing the temperature [48]. Increasing the temperature can overcome the activation energy of the reaction and promote the adsorption reaction; increasing the temperature also increases the molecular thermal motion in the system and facilitates the adsorption reaction.…”

Red mud (RM) is an industrial waste produced in large amounts during alumina extraction from bauxite. Its disposal generates serious environmental pollution due to high alkalinity. Therefore, a strategy for the effective utilization of RM must be developed. For instance, RM may be transformed into useful products, such as adsorbents. Given its high concentrations of aluminum oxides, iron oxides, titanium oxides, silica oxides, and hydroxides, RM may be developed as a cheap adsorbent for the removal of various ions from aqueous solution and soils (e.g., metal and non-metal ions, phenolic compounds, and dyes) and waste gas purification (sulfide and carbide). This review summarizes the background, properties, and applications of RM as an adsorbent. Proper approaches of removing metal and non-metal elements from wastewater are also systematically reviewed and compared. Emphasis is placed on the surface modification of RM to obtain high adsorption. Finally, the scope for future research in this area for RM is discussed in depth.
