Biosorption of fluoride on Neem (Azadirachta indica) leaf powder

Effective Parameters, Equilibrium, and Kinetics of Fluoride Adsorption on Prosopis cineraria and Syzygium cumini Leaves

“…The maximum biosorption capacities of the PCL and SCL were obtained 11.52 and 7.40 mg/g, respectively. The biosorption capacities of the studied adsorbents are greater than those obtained for dried Indian sandalwood (4.66 mg/g) and Azadirachta indica (4.7 mg/g) but lower than Pleurotus eryngii (66.6 mg/g) .…”

Activated carbon/NiFe2O4 magnetic composite: A magnetic adsorbent for the adsorption of methyl orange

“…not the only rate-controlling step and the external mass transfer is 507 also occurring simultaneously [62]. The overall adsorption process 508 may be jointly controlled by external mass transfer and intra-509 particle diffusion [63]. 510 In order to prove the rate-dominating step in adsorption is 511 particle diffusion or external mass transfer, the adsorption kinetic …”

“…Ai et al synthesized AC/CoFe 2 O 4 composite by a simple one- 58 step refluxing route and the adsorption property of AC/CoFe 2 O 4 59 composite was investigated as magnetic adsorbent for the removal 60 of malachite green from water [22]. Zhang et al developed a 61 magnetic adsorbent CuFe 2 O 4 /AC using a simple chemical copre- 62 cipitation procedure and its adsorption property was investigated 63 for the removal of acid Orange II [23]. Zhu et al successfully 64 prepared the magnetic cellulose/Fe 3 O 4 /AC composites and inves- 65 tigated its adsorption property toward congo red [24].…”

Enhanced defluoridation and facile separation of magnetic nano-hydroxyapatite/alginate composite

“…However, it possesses limitations like low removal capacity, stability, etc. The biopolymer supported inorganic composites has significant attention in recent years for fluoride removal as it possess the high uptake capacity than the base components [11][12][13][14][15][16][17][18].…”
