Characterization and evaluation catalytic efficiency of La0.5Ca0.5NiO3 nanopowders in removal of reactive blue 5 from aqueous solution

Adsorption of Methylene Blue from Aqueous Solution Using Steam-Activated Carbon Produced from <i>Lantana camara</i> Stem

“…However, most of these methods for the removal of dyes from dye containing wastewater have serious restrictions such as high cost, formation of hazardous by-products or intensive energy requirements [5] [6]. Therefore, the development of efficient, low-cost and environmentallyfriendly technologies to reduce dye content in wastewater is extremely necessary.…”

Fabrication of perovskite-type oxide La0.5Pb0.5MnO3 nanoparticles and its dye removal performance

“…The equilibrium adsorption can be described using Freundlich model. This adsorbent exhibits either comparable or better performance to the existing adsorbents, already reported by researchers for dye removal from aqueous solutions [17,35,36]. Therefore, these nanoperovskite-type oxides are promising candidates for the adsorption of different dyes from wastewaters.…”

“…The perovskite precursor in this work was prepared by the citrate-based sol-gel modified pechini method [17]. Reagents of La(NO 3 ) 3 .6H 2 O, C 6 H 9 MnO 6 .2H 2 O, Pb(NO 3 ) 2 and citric acid (99.5 %) were used as starting materials.…”

Synthesis and Evaluation Catalytic Efficiency of Perovskite-Type Oxide Nanopowders in Removal of Bromocresol Purple from Aqueous Solution

“…Compared with the other conventional wastewater treatment means, this technology has such advantages as: 1) wide application, especially to the molecule-structure complexed contaminants which cannot be easily degraded by the traditional methods; 2) the nanoparticles itself has no toxicity to the health of our human livings and 3) it demonstrates a strong destructive power to the pollutants and can mineralize the pollutants into CO2 and H2O. Due to the excellent features of this technology, it appears promising and has drawn the attention of researchers of at home and abroad (Tavakkoli et al, 2013;Yazdanbakhsh et al, 2011;Carbajo et al, 2006).…”
