“…Different methods have been researched and developed for the recovery and reduction of vanadium pollution, these include: ion exchange resins (Gomes et al., 2016; Yeom et al., 2009); leaching (Cappuyns and Swennen, 2014; Chen et al., 2010); and gravity separation (Zhao et al., 2013). However, leaching process requires elevated concentration of the acid and temperatures (Cappuyns and Swennen, 2014), while ion exchange is not a desirable method for removing low metal concentrations (Uddin, 2017).…”

The use of adsorption using nanomaterials has become a very competitive method for removal of hazardous materials from wastewater. With increasing consumption of fossil fuels and development of energy storage systems, the levels of vanadium pollution are expected to increase. Utilizing natural shale and coal waste as adsorbents, batch adsorption, isotherms, and kinetics of vanadium was studied. The adsorption characteristics of shale and coal waste were studied using Fourier Transform Infrared spectroscope and Scanning Electron Microscopy. The effect of pH, the amount of adsorbent, vanadium concentration, temperature, and contact time between adsorbate and adsorbents were also studied to obtain optimum conditions for maximum adsorption of vanadium. The Fourier Transform Infrared results show little distortion in the vibration of bands, and hence the surface properties remain unchanged for both sorbents after adsorption. The adsorption kinetics are best described by pseudo-second order, while Langmuir model fits the adsorption isotherm for both adsorbents. Maximum sorption capacity is 67.57 mg/g for shale while that of coal is 59.88 mg/g at 298 K and pH 3. For both adsorbents, the adsorption process is spontaneous, endothermic, and chemisorption in nature. Both adsorbents can effectively be recycled twice.

“…Vanadium (V) is an abundant element in the earth crust [1] and widely used in various industrial processes, such as ceramic, glass, textile and so on [2]. Vanadium can accumulate in soil through parent rock weathered, combustion of fossil fuels, wet or dry deposition or draining by waste water and so on [3,4].…”

Greenhouse experiments were conducted to study the permissible value of vanadium (V) based on the growth and physiological responses of green Chinese cabbage (Brassica chinensis L.), and effects of V on microbial biomass carbon (MBC) and enzyme activities in allitic udic ferrisols were also studied. The results showed that biomass of cabbage grown on soil treated with 133 mg V kg(-1) significantly decreased by 25.1% compared with the control (P < 0.05). Vanadium concentrations in leaves and roots increased with increasing soil V concentration. Contents of vitamin C (Vc) increased by 10.3%, while that of soluble sugar in leaves significantly decreased by 54.0% when soil V concentration was 133 mg kg(-1), respectively. The uptake of essential nutrient elements by cabbage was disturbed when soil V concentration exceeded 253 mg kg(-1). Soil MBC was significantly stimulated by 15.5%, while dehydrogenase activity significantly decreased by 62.8% and urease activity slightly changed at treatment of 133 mg V kg(-1) as compared with the control, respectively. Therefore, the permissible value of V in allitic udic ferrisols is proposed as 130 mg kg(-1).

“…Therefore, the ideal loading pattern would be attained by simply increasing the reaction temperature. Yeom et al 68 found that the equilibrium adsorption capacity of vanadium to the ion exchangers was slightly increased, at the same time, the rate constant was increased twice with increasing temperature from 10 • C to 40 • C. Moreover, Azizian and Yahyaei 69 also reported that the rates of 18-crown-6 adsorbed onto granular activated carbon at 25 • C and 45 • C were higher than that at 15 • C. These are consistent with our experiment results.…”
