ResumenSe analizó la capacidad de remoción de arsénico (As V) en solución acuosa por la biomasa modificada del hongo Aspergillus niger, por espectrometría de absorción atómica. La contaminación por arsénico es muy grave en México, afecta a casi todas las poblaciones, y las técnicas de remoción son muy caras y no tan eficientes. En los estudios, la mayor bioadsorción (69% con 1 mg L -1 del metaloide) fue a las 24 horas, a pH de 6.0, 28 o C y 1 g de biomasa modificada. Con respecto a la temperatura, la más alta remoción fue a los 28 o C, con un 69% de remoción a las 24 horas. A mayor concentración de arsénico fue menor la remoción, y al aumentar la concentración del bioadsorbente, la remoción es más eficiente (96% con 5 g de biomasa). Además se remueve eficientemente el metaloide in situ (56% de remoción en agua natural contaminada con 1 mg 100 mL -1 de As (V) en 24 horas con 1 g de biomasa). Por lo tanto, la biomasa modificada se puede utilizar para eliminar el arsénico de aguas residuales industriales. Palabras clave: bioadsorción; arsénico; biomasa celular fúngica modificada; biorremediación Removal of Arsenic /V) in Aqueous Solution by Modified Fungal Biomass of Aspergillus nigerThe removal capacity of arsenic (As V) in aqueous solution by the modified fungal biomass of Aspergillus niger, by atomic absorption spectrometry, was analyzed. Arsenic contamination is very serious in Mexico, it affects almost all populations, and the removal techniques are very expensive and not very efficient. In this study, the highest bioadsorption (69% with 1 mg L -1 of the metalloid) was at 24 hours at pH 6.0, 28 o C and 1 g of modified biomass. With respect to the temperature, the highest removal was at 28 o C, with a 69% removal in 24 hours. At higher concentration of arsenic the removal was lower, and by increasing the concentration of the bioadsorbent, the removal is more efficient (96% with 5 g of biomass). Additionally, the biomass efficiently removes the metalloid in situ (56% removal in natural water contaminated with 1 mg 100 mL -1 of As (V) in 24 hours with 1 g of biomass). Therefore, the modified biomass can be used to eliminate arsenic from industrial wastewater.

Permeable reactive barriers (PRBs) are an environmentally-friendly, cost-effective insitu technology that can be used to remediate polycyclic aromatic hydrocarbons (PAHs)-contaminated groundwater. In this study, PRB of two various materials (A and B) that relied on microbes self-domestication mechanism were designed and tested. The materials A and B were the same apart from their carbon source: A was based on wheat straw and B was based on coconut shell biochar. We used laboratory batch experiments followed by long-term column tests to assess the capacity of these two materials to remediate PAHs. The results showed that both A and B removed almost 100% of the phenanthrene. More carbon was released from A (80-500 mg/L) than from B (72-195 mg/L), and slightly more oxygen was released from B (7.31-10.31 mg/L) than A (7.15-9.64 mg/L). The release of organic carbon from material B was more stable than that from material A. The bacterial communities of both columns comprised members of the Mycobacterium, Pseudomonas, and Sphingomonas genera that are known to degrade phenanthrene, and Pseudomonas and Sphingomonas were 7 times more abundant in column B than in column A. Material B is more promising for treating PAH-contaminated groundwater than material A.

“…Commonly used media that is classified as inorganic minerals-based PRB are limestone, apatite, concrete, manganese, zeolite, and magnesite [34][35][36][37][38]. These materials are composed of calcium, sodium, magnesium and manganese-based minerals which are responsible for the increase in the alkalinity.…”

A systematic mapping study on the development of permeable reactive barrier for acid mine drainage treatment

Acid mine drainage is a result of exposure of sulfide ore and minerals to water and oxygen. This environmental pollutant has been considered the second biggest environmental problem after global warming. On the other hand, permeable reactive barrier is an emerging remediation technology which can be used to treat acid mine drainage. However, the effectiveness of this proposed remediation technology greatly depends on the reactive media. Also, treatment of acid mine drainage using permeable reactive barrier is still in the infancy stage, and long-term performance is still unknown. Hence, this study was conducted to identify what have been studied, addressed and what are currently the biggest challenges and limitations on the use of permeable reactive barrier for acid mine drainage treatment. Through systematic mapping approach, the results have shown that the reactive media used in permeable reactive barrier can be categorized into five namely iron-based, organic-based, inorganic minerals-based, industrial waste-based, and combined media. The data revealed that majority of the papers which is about 40% use combined media as the reactive substrate. The future direction is toward the use of combined media as a reactive material for AMD treatment, for instance, use of geopolymer with mine tailings and silts as reactive media in combination with organic-based media
