The removal of methylene blue dye using low-cost biosorbents is therefore highly recommended.…”

Invasive plants as biosorbents for environmental remediation: a review

Water contamination is an environmental burden for the next generations, calling for advanced methods such as adsorption to remove pollutants. For instance, unwanted biowaste and invasive plants can be converted into biosorbents for environmental remediation. This would partly solve the negative effects of invasive plants, estimated at 120 billion dollars in the USA.Here we review the distribution, impact, and use of invasive plants for water treatment, with emphasis on the preparation of biosorbents and removal of pollutants such as cadmium, lead, copper, zinc, nickel, mercury, chromate, synthetic dyes, and fossil fuels. Those biosorbents can remove 90-99% heavy metals from aqueous solutions. High adsorption capacities of 476.190 mg/g for synthetic dyes and 211 g/g for diesel oils have been observed. We also discuss the regeneration of these biosorbents.

Decolorization of Reactive Black 5 (RB5) was investigated by heterogeneous photocatalysis using N-doped TiO2. N-doped TiO2 photocatalysts were synthesized by means of a sol-gel process. X-ray diffraction performed the characterization of synthesized samples, scanning electron microscopy and X-ray photoelectron spectroscopy measurements. Photocatalytic activity of N-doped TiO2 samples was assessed by following decolorization and degradation efficiency of RB5. N-TiO2(3) sample yielded the highest decolorization efficiency. The apparent first-order rate constants for decolorization of RB5 with N-TiO2(X) samples followed the order of N-TiO2(3) > N-TiO2(2) > N-TiO2(4) > N-TiO2(1). Improvement of decolorization efficiency of TiO2 was observed doping with nitrogen. The effect of actual sunlight on decolorization efficiency was also investigated. 96% and 49% of decolorization efficiency levels were attained within 60 minutes of reaction time with outdoor sunlight and fluorescent daylight lamps, respectively.

In the present study, the successful fabrication, through a surfactant-free one-pot synthesis in ethanol solution, of the all-inorganic halide perovskite CsPbBr3 has been achieved. The phase formation has been obtained for the first time, using the β-diketonate complexes [Pb(hfa)2diglyme]2 and Cs(hfa) (Hhfa = 1,1,1,5,5,5-hexafluoro-2,4-pentanedione; diglyme = 2-methoxyethyl ether) and Br2 as the precipitating agent. The growth of CsPb2Br5 microcrystals has been obtained and stabilized under specific synthetic conditions, by controlling the phase transition from CsPbBr3 to CsPb2Br5 as well. The entire process was operated under acid-catalyzed conditions without any need of humidity control and hazardous organic solvents. The control of the aging time and the phase stability during the heat treatment represent the key points in order to selectively and reproducibly obtain the CsPbBr3 or CsPb2Br5 phases. Structural, morphological, and compositional characterizations of the final product show the formation of square microcrystals, with a grain size of up to 3 μm, of the pure and stable perovskite CsPbBr3 phase. Finally, promising results in photocatalytic degradation tests using rhodamine B solution have been obtained under UV light (λ = 360 nm) and visible light, showing high degradation yields of up to 81.9% and 58.4% for CsPbBr3 and CsPb2Br5, respectively.
