Synthesis of magnetic chrysotile nanotubes for adsorption of Pb(II), Cd(II) and Cr(III) ions from aqueous solution

Recycling flue gas desulphurization (FGD) gypsum for removal of Pb(II) and Cd(II) from wastewater

“…9(a), the TCLP-Pb in the unamended soil was almost 16.4 times higher than the USEPA regulatory level of 5 mg/L. The addition of FGD gypsum at higher rates was more effective to decrease the TCLP-Pb concentrations, and the TCLP-Pb concentration in the soil treated with 20% FGD gypsum [29], NSNHS: amino functionalized silica nano-hollow sphere [30], NSG: amino functionalized silica gel [30], S83N: porous silica modified with N 1 -(3-trimethoxysilylpropyl) diethylenetriamine [30], MChNTs: magnetic chrysotile nanotubes [29], CNT: multiwalled carbon nanotubes [31], S15RN: amine-grafted SBA-15 [30], GNSC8P: functionalized graphene [31]). decreased to below 5 mg/L.…”

Cation Redistribution along the Spiral of Ni‐Doped Phyllosilicate Nanoscrolls: Energy Modelling and STEM/EDS Study

“…Single-walled and multi-walled nanotubes and nanoscrolls formed by this process have a range of interesting properties and related applications. The inner channel grants large specific surface area (up to 400 m 2 /g) [5,13] as well as active sites for adsorption [14,15] and encapsulation of functional substance. [16,17] The outer and inner hydrosilicates surfaces saturated with OHgroups can be modified by various organic compounds as well as be decorated by metallic or oxide phases.…”

Pb(II) adsorption on magnetic γ-Fe2O3/titanate nanotubes composite

“…Heavy metals in aquatic environment represent a potential risk 8 to human beings and the resulting pollution has attack worldwide 9 concern. As a typical heavy metal, Pb(II) is considered to be one of 10 the most toxic heavy metals and the exposure to Pb(II) can cause 11 serious disease [1,2].…”

“…The key to adsorption is the adsorbent; appropriate 19 adsorbent can achieve excellent Pb(II) removal efficiency. Recently, 20 many novel and modified adsorbents have been developed for the 21 Pb(II) removal, such as copper oxide (CuO) nanorods [9], acid- 22 activated clay [10], Co 0 . 6 Fe 2 .…”
