dc.description.abstract | Herein, Taguchi L9 orthogonal array was used for the first time to optimize synthesis of diametercontrolled multi walled carbon nanotubes (MWCNTs). The nanoadsorbents, MWCNTs5 15 nm and MWCNTs16 25 nm were applied for Pb(II) and Ni(II) ion removal from paint, battery and electroplating wastewater. The results indicated successful synthesis of MWCNTs with diameter distribution ranges of 5 e15 nm and 16e25 nm. The synthetized smaller diameter MWCNTs5 15 nm revealed higher Brunauer- Emett-Teller (BET) surface area of 1306 ± 5 m2/g compared to larger diameter MWCNTs16 25 nmwith the surface area of 1245 ±4m2/g. They demonstrated excellent adsorption of Pb(II) and Ni(II) ions within the permissible concentration proposed by WHO at pH, contact time, adsorbent dosage and temperature of 5, 60 min, 30 mg/L and 50 C, respectively. Particularly, MWCNTs5 15 nm possessed high adsorption capacity of 215.38 ± 0.03 mg/g for Pb(II) and 230.78 ± 0.01 mg/g for Ni(II). Again, the maximum adsorption capacity of 201.35 ± 0.02 and 206.40 ± 0.02 mg/g was achieved for Pb(II) and Ni(II) using MWCNTs16 25 nm. All in all, the adsorption capacity of the nanoadsorbents at the investigated diameter range showed higher efficiency compared to other materials for heavy metals elimination from chemical industrial wastewater | en_US |
