Rice hull/MnFe2O4 composite: Preparation, characterization and its rapid microwave-assisted COD removal for organic wastewater

Na0.5Li0.5CoO2 nanopowders: Facile synthesis, characterization and their application for the removal of methylene blue dye from aqueous solution

“…Different amounts of NPs (0.01-0.04 g) were added into the reactor containing 10 ml aqueous solution of MBD (50 mg L À1 ) and the experiments were done at different temperatures (15, 25, 35 and 45°C), and pH (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11). Sample was taken out and centrifuged for analysis by a UV-vis spectroscopy at different time intervals.…”

“…Several articles have investigated the effectiveness of spinel [9,10] and perovskite [11,12] oxides as adsorbent for removal of water-soluble dyes. Yazdanbakhsh et al [13] evaluated the effectiveness of LiCo 0.5 Fe 0.5 O 2 powder as an adsorbent/catalyst material for the removal of Reactive blue 5 (RB5).…”

Trace Analysis of Carbazole in Commercial Diesel by using Adsorption on Activated Biochar from Rice Husk Pyrolysis

“…Actually, any carbonaceous material with high carbon content can be used as raw material for the preparation of activated carbons (ACs) [1]. This is the case of t agricultural solid wastes [2] , such as, cotton stalk [3,4], tobacco stem [5], rice husk [6], cork [7], bamboo [8], waste tea [9,10], coconut shell [11], oil palm fiber [12], durian shell [13], wood [14], sisal [15] and many others.…”

Synthesis of rambutan-like MnCo2O4 and its adsorption performance for methyl orange

“…Spinel ferrites (MFe 2 O 4 , M = transition metal and/or alkaline earth metal) behave with ferromagnetic property at room temperature. So, they have been widely used as the magnetic carrier in adsorbent to realize magnetic separation [19,20] [26], and Fe 3 O 4 [27]. However, the adsorption capacity of ferrites is far lower than that of the activated carbon in recent reports due to small specific surface area of ferrites.…”
