“…Soil contaminated with petroleum can be a source of heavy metals particularly mercury (Chaturabul et al, 2015). Mercury is available in the natural gas and crude oil in different quantities depending on the geological location, where it is ranging between 0.01 ppb up to 10 ppm (Wilhelm and Bloom, 2000).…”

“…Mercury found in crude oil, in different forms elemental, organic, mercuric halides, and mercury (sulfur) complexes, where the solubility of these different forms depend mainly on the temperature (Wilhelm and Bloom, 2000). Moreover mercury is not only being found in the crude oil but also found within the ''produced water" which is associated with the petroleum, having a damaging effect on the facilities used in extracting the petroleum, and this effect might extend and affect workers in the petroleum industry causing mercury poisoning (Chaturabul et al, 2015). In the present study, all bacterial strains that are active in mercury bio-uptake were isolated from a soil contaminated with petroleum.…”

“…HgS) (Latif and Amin, 2011;Cho et al, 2013;López et al, 2015). Therefore, microbial bioremediation is an interesting methodology for mercury remediation and it appears as an attractive methodology owing to its low cost, simple, and environmental friendly (WagnerDobler, 2013;Chaturabul et al, 2015). Green biotechnology may have a safer way to reduce the toxicity of mercury.…”

A mathematical model was developed for the germanium facilitated transport from a medium containing tartaric acid using Alamine 336 as a carrier. Modeling was carried out based on the extraction constant (K ext) obtained from the liquid-liquid extraction (LLX) modeling. The LLX data was achieved from experiments with conditions being Alamine 336 concentrations of 0.1-10 %v/v from a solution containing about 1.378 mmol/L Ge (100 mg/L) and tartaric acid as an anionic complexant. The LLX model was attained using the equilibrium-based procedure and fitted to extraction experimental data for various carrier concentrations. This model presented an accurate extraction constant (K ext =0.02) used in the facilitated transport modeling. The flat sheet supported liquid membrane (FSSLM) experiments were conducted in the condition of 1.378 mmol/L Ge (100 mg/L), tartaric acid concertation of 2.760 mmol/L, 1 M HCl as a stripping phase and various Alamine 336 concentrations in the range of 0 to 35 %v/v. The FSSLM model was developed according to the Fick's law, the diffusional transport, and equilibrium equations. According to the model, mass transfer and diffusion coefficients for various concentrations of the carrier were found. In addition, the calculated and experimental values had a good correlation with together showing the validity of the model. This model can be used in the further process simulation such as hollow fiber SLMs.

“…Mercury needs to be reduced to its elemental state (Hg 0 ) following chemical leaching. Processes such as cementation, electroplating/ electrorecovery, ultrafiltration, ion exchange, solvent extraction, and biodegradation/bioreduction were reported to be used for such a purpose, and mercury would be neutralized and then recovered through the hybrid use of these processes (Chaturabul et al 2015). The most frequently used process for the recovery of mercury from industrial wastes is cementation.…”

In this work, the recovery of mercury from spent fluorescent lamps by oxidative leaching followed by cementation process was studied. Two different reactive solutions (NaOCl/NaCl and KI/I 2 ) during oxidative leaching were investigated whereas at the cementation process, metallic powders of iron (Fe), copper (Cu), and zinc (Zn) were used as reducing agents to capture mercury in solid phase. Mercury could be transferred to the solution with an efficiency of 96 % from the spent lamp samples through the NaOCl/NaCl reagent. The optimal leaching conditions were determined as 2-h contact time, 120 rpm agitation speed, pH 7.5, and 50°C of temperature. The reducing agent, Zn, provided 99 % of the cementation. The optimal process conditions were observed to be as 5-min contact time, pH 1, and 5 g L −1 of reducing agent concentration. This combined approach appears to be technically effective for the recovery of mercury from spent fluorescent lamps.
