“…Aqueous solutions of Pb(II) with required concentrations (10,20,50,100,200, 300 and 500 mg L -1 ) were prepared by dissolving Pb(NO3)2 in Milli-Q water followed by subsequent dilutions. These concentrations were within the typical Pb concentration ranges found in contaminated acid mine drainage water (Lottermoser, 2010). Batch adsorption experiments of palygorskite-iron oxide nanocomposite (Pal-IO), pristine palygorskite (Pal) and iron oxide (IO) were conducted (experimental condition: 25°C, pH 5, 5 g L -1 adsorbent loading, 150 agitations per min, contact time of 12 h) in capped polypropylene tubes at a pre-determined Pb(II) concentration.…”

A palygorskite-iron oxide nanocomposite (Pal-IO) was synthesized in situ by embedding magnetite into the palygorskite structure through co-precipitation method. The physico-chemical characteristics of Pal-IO and their pristine components were examined through various spectroscopic and micro-analytical techniques. Batch adsorption experiments were conducted to evaluate the performance of Pal-IO in removing Pb(II) from aqueous solution. The surface morphology, magnetic recyclability and adsorption efficiency of regenerated Pal-IO using desorbing agents HCl (Pal-IO-HCl) and ethylenediaminetetraacetic acid disodium salt (EDTA-Na) (Pal-IO-EDTA) were compared. The nanocomposite showed a superparamagnetic property (magnetic susceptibility: 20.2 emu g) with higher specific surface area (99.8 m g) than the pristine palygorskite (49.4 m g) and iron oxide (72.6 m g). Pal-IO showed a maximum Pb(II) adsorption capacity of 26.6 mg g (experimental condition: 5 g L adsorbent loading, 150 agitations min, initial Pb(II) concentration from 20 to 500 mg L, at 25 °C) with easy separation of the spent adsorbent. The adsorption data best fitted to the Langmuir isotherm model (R = 0.9995) and pseudo-second order kinetic model (R = 0.9945). Pb(II) desorption using EDTA as the complexing agent produced no disaggregation of Pal-IO crystal bundles, and was able to preserve the composite's magnetic recyclability. Pal-IO-EDTA exhibited almost 64% removal capacity after three cycles of regeneration and preserved the nanocomposite's structural integrity and magnetic properties (15.6 emu g). The nanocomposite holds advantages as a sustainable material (easily separable and recyclable) for potential application in purifying heavy metal contaminated wastewaters.

“…Neutral mine drainage is a common environmental disturbance in mining areas. It is an aqueous solution derived from the oxidation of minerals, and is generally rich in calcium, sodium, magnesium, and heavy metals ( Rose and Cravotta, 1998 ; Lottermoser, 2007 ). However, neutral mine drainage environments remain poorly explored, and little is known about the structures and diversity of the bacterial communities present ( Liao and Xie, 2007 ; Guo et al ., 2009 ).…”

Characterization of the core microbiota of the drainage and surrounding soil of a Brazilian copper mine

2015

The core microbiota of a neutral mine drainage and the surrounding high heavy metal content soil at a Brazilian copper mine were characterized by 16S rDNA pyrosequencing. The core microbiota of the drainage was dominated by the generalist genus Meiothermus. The soil samples contained a more heterogeneous bacterial community, with the presence of both generalist and specialist bacteria. Both environments supported mainly heterotrophic bacteria, including organisms resistant to heavy metals, although many of the bacterial groups identified remain poorly characterized. The results contribute to the understanding of bacterial communities in soils impacted by neutral mine drainage, for which information is scarce, and demonstrate that heavy metals can play an important role in shaping the microbial communities in mine environments.

This research digs into the convoluted topography of water contamination in Zambia's Copperbelt Province, with an emphasis on the important contributions of mining and sewage effluent. This report provides major conclusions about the origins, types, and effects of contaminants in the region's water bodies based on a thorough review of current research and empirical evidence. Mining activities emerge as a major source of water pollution, with effluent contaminated with heavy metals, sulphates, and other compounds that pose serious hazards to aquatic ecosystems and public health. Despite efforts to improve wastewater treatment, shortcomings persist, resulting in the leakage of toxic effluent into neighboring waterways. Similarly, sewage wastewater contributes to contamination by including faecal coliforms, nutrients, oils, and heavy metals. The effects of water contamination are far-reaching, as indicated by increasing pollutant concentrations in stream sediments and downstream bodies. Aquatic life suffers from habitat destruction, diminished biodiversity, and negative health effects, while communities relying on these water supplies face increased health risks. Given these issues, the paper analyses potential solutions and recommendations for effective wastewater management, with a focus on interdisciplinary collaboration, technical innovation, and regulatory enforcement. Initiatives fostering recycling, resource recovery, and the implementation of advanced treatment technology hold promise for minimizing water pollution and maintaining sustainable water management practices in the Copperbelt Province.
