“…In relation to techniques for reducing arsenic, there is a predominant line based on the use of iron. Among these techniques, some of them should be highlighted: Co-precipitation and natural adsorption by iron minerals [34,35], electrocoagulation using iron electrodes [36], use of iron-rich sludge from coal treatment [37], sorption using coconut shell and iron oxide-coated sand [38], and biogenic ferric precipitates [39]. There are also biotic arsenic removal techniques, such as bioleaching using Acidothiobacillus thiooxidans.…”

The aim of this study is to evaluate the application of the main hazardous waste management techniques in mining operations and in dumping sites being conscious of the inter-linkages and inter-compartment of the contaminated soils and sediments. For this purpose, a systematic review of the literature on the reduction or elimination of different potential toxic elements was carried out, focusing on As, Cd and Hg as main current contaminant agents. Selected techniques are feasible according to several European countries’ directives, especially in Spain. In the case of arsenic, we verified that there exists a main line that is based on the use of iron minerals and its derivatives. It is important to determine its speciation since As (III) is more toxic and mobile than As (V). For cadmium (II), we observed a certain predominance of the use of biotic techniques, compared to a variety of others. Finally, in mercury case, treatments include a phytoremediation technique using Limnocharis flava and the use of a new natural adsorbent: a modified nanobiocomposite hydrogel. The use of biological treatments is increasingly being studied because they are environmentally friendly, efficient and highly viable in both process and energy terms. The study of techniques for the removal of potential toxic elements should be performed with a focus on the simultaneous removal of several metals, since in nature they do not appear in isolation. Moreover, we found that energy analysis constitutes a limiting factor in relation to the feasibility of these techniques.

“…Meanwhile, the relevance of V, O, S, and Fe indicated that the vanadium indeed existed in jarosite. Sarita H. Ahoranta et al [34] adopted a simple approach Research about the removal of vanadium from aqueous solutions has indicated that vanadium can be effectively removed by co-precipitation with iron (III) [31,32]. The removal mechanism of vanadium could be explained by a formal co-precipitation intended as the incorporation of vanadium in the iron particles formed by the addition of iron (III) and/or adsorption of vanadium on the iron (hydr)oxides surface [33].…”

Washing precipitates with dilute acid, metals adsorbed by jarosite may be released to the liquid phase.…”

Vanadium Bioleaching Behavior by Acidithiobacillus ferrooxidans from a Vanadium-Bearing Shale

et al. 2018

This study investigated bioleaching behavior of vanadium from a vanadium-bearing shale using Acidithiobacillus ferrooxidans (A. ferrooxidans). Results showed a maximum recovery of 62% vanadium in 1.2-day bioleaching, which was 22.45% higher than the controls. Then, the vanadium leaching efficiency decreased significantly, only 24% of that was obtained on the tenth day. The vanadium extraction in 1.2 days was mainly attributed to the dissolution of vanadium in free oxides of shale. Fe 3+ produced by A. ferrooxidans promoted the dissolution process. X-ray diffraction (XRD) patterns of the leached residues confirmed the generation of jarosite. SEM-EDS analysis of the residues indicated that jarosite adsorbed on the shale and inhibited the further dissolution of vanadium. The relevance of V, Fe, S, O was quite good in the energy disperse X-ray spectrometry (EDS) element mapping of jarosite, and acid-washing of the jarosite resulted in 31.6% of the vanadium in the precipitates desorption, indicating that the decrease of vanadium leaching efficiency in bioleaching process was caused by both adsorption and co-precipitation with jarosite.

“…Several chemical methods such as coagulation, adsorption, precipitation, ion exchange, membrane filtration, and biological methods such as biomass and biofiltration have been developed to remove heavy metals from aqueous solutions (9,10). In the recent years, agricultural wastes as an adsorbent have received much attention due to the functional groups on the surface of these materials (11).…”

The arsenite species is a common form of arsenic in nature and ground waters and is categorized as a major public health group. In the present study, the arsenite ions from contaminated solutions were removed by adsorption on the granola modified lemon peel. The arsenite adsorption on lemon peel was investigated by various concentrations of arsenite with 0.2 g/100 mL of adsorbent at a range of pH 3 - 10 and a constant temperature of 25°C for 0 to 240 minutes using batch experiments. Data of the adsorption experiment were analyzed by the pseudo-first and second- order kinetic equations. The Freundlich and Langmuir isotherm models were used to understand the adsorption relationship between the arsenite ions and functional groups on the lemon peel. pH equal to 5.2 was recorded as pHzpc of this adsorbent in aqueous solution. The optimum condition was obtained at 60 minutes, pH value 8, and 2 mg/L of arsenite, with a removal efficiency of 88%. The maximum adsorption capacity of granola lemon peel was 27 mg.g-1 in Langmuir model. Lemon peel adsorbent presented good removal efficiency for arsenite in contaminated aqueous solutions and real water.
