“…Como era de esperarse la capacidad de intercambio iónica de estos residuos se encuentra muy por debajo de los valores encontrados para otras fases minerales y zeolitas con alta capacidad de intercambio (caolinita, 3-15 meq/100g; vermiculita 100-150 meq/100g, bentonita, 100 meq/100g, faujasita, 390 meq/100g, mordenita 230 meq/100g) [10] como se muestra en la Tabla 3.…”

“…Por lo que se refiere al cromo, este es uno de los metales de mayor uso a nivel industrial, puesto que está involucrado en gran variedad de procesos como curtientes, pigmentos y conservantes textiles, aleaciones, pinturas, catalizadores, agentes anticorrosivos, fungicidas, conservantes de madera, recubrimientos metálicos, electrogalvanizados, entre otros [10]. Actualmente, no se encuentran tecnologías necesarias para la remoción de este metal en aguas residuales, inclusive se han encontrado procesos industriales en los cuales no se presenta ningún control de este contaminante en los residuos.…”

In this paper, the process for the synthesis of LTA and/or FAU zeolites from waste materials from mining and manufacturing industry from Antioquia (Colombia) was described. The product was used as adsorbent for the removal of Cr (III) in solutions prepared in the laboratory. The waste materials were characterized by X-ray fluorescence, and X-ray diffraction. The zeolites were characterized by X-ray diffraction, X-ray fluorescence, scanning electron microscopy (SEM) and BET area. Absorption data in Cr(III) removal tests were obtained by elemental composition from atomic absorption spectroscopy, and evaluated by Langmuir, Freundlich and Temkin models, and four kinetics models. The results showed the formation of zeolites from waste materials, and effective in adsorption tests of Cr (III).

“…Chromium contamination of soils and irrigation water remains a matter of concern [1], with increased health risks in humans due to the food-chain contamination. A fertilizer plant site usually has a soil contamination of ∼700 mg/Kg and in industrial/tannery effluents/soils may reach 5000-45,000 mg/Kg (reviewed by Shahid et al [1]).…”

“…A fertilizer plant site usually has a soil contamination of ∼700 mg/Kg and in industrial/tannery effluents/soils may reach 5000-45,000 mg/Kg (reviewed by Shahid et al [1]). Chromium's most stable oxidation forms are Cr(III) and Cr(VI), both having different mobility, bioavailability, and toxicity [2].…”

Chromium (Cr) contamination in arable soils and irrigating water remains a priority, particularly due to the challenges posed to crop production and food safety. Long-term Cr(VI) effects remain less addressed than short-term ones, particularly regarding organspecific genotoxic profiles. Here we used the crop Lactuca sativa growing in a protected horticultural system and irrigated for 21 days with Cr(VI) (up to 200 mg/L). Besides the oxidative stress, the genotoxicity was evaluated. Shoots and roots showed distinctive oxidative stress status and genotoxic effects, in a dose-dependent manner. While 50 mg/L stimulated antioxidant activities and no major genotoxic effects were found, plants exposed to ≥150 showed an increase of oxidative disorders, together with cytostatic and DNA damage effects, and some mitotic impairment. Leaves showed less oxidative signs at 50 mg/L, while at 150/200 mg/L the antioxidant battery was stimulated. In Cr treated plants, the highest dose increased the DNA damage, reinforcing the idea that DNA breaks were related to mitotic disorders in higher doses. In conclusion, long-term exposure data show a highly responsive root, with a quadratic response meaning higher defenses at lower Cr doses, and higher oxidative and DNA damage and cytostatic effect at a higher dose.

“…The REE elements analysed (Ce, Eu, La, Lu, Sm, Sc and Yb) were found to correlate with each other and with Na, Fe, Hf, Cr and Th. This is called the 'Iron Factor' in biogeochemical studies (Dunn, 1995a which causes it to exhibit variable behaviour dependent upon pH, oxidative properties of the surrounding area and the soil's microbial action (Shahid et al, 2017).…”
