Studies on the capability and behavior of adsorption of thallium on nano-Al2O3

Synthesis of nano B2O3/TiO2 composite material as a new solid phase extractor and its application to preconcentration and separation of cadmium

“…Recently nanomaterials have been used as sorbent due to their improved intrinsic properties such as chemical activity and fine grain size in compared with the classical substances such as normal scale titanium dioxide, alumina, etc. [14][15][16]. Nanomaterials have high surface areas and therefore, they can strongly adsorb many substances such as trace metals [17] and polar organic substances [18].…”

Efficient electrochemical oxidation of thallium (I) in groundwater using boron-doped diamond anode

“…Thus a 42 3 simple, efficient way of treating Tl-contaminated groundwater is urgently needed. 43 Nowadays, electrochemical oxidation technology is considered a green, efficient 44 method for the removal of contaminants from soil and water, owing to the strong 45 oxidative oxidants produced during electrolysis [14,15]. To date, electrochemical 46 process has been widely used for remediation of metal-contaminated aqueous systems, 47 with various metals as targets, including As, Pb, V, Cd [16][17][18] stronger direct electrochemical oxidation, and more active substances could also be 170 produced, both of which could promote the removal of Tl(I) [46].…”

“…(6), (7), (8), (9)) . Tl(I) could, in principle, be easily oxidized to Tl(III) in acidic condition [45]. It should (from 2.00 to 2.07), thus subsequent treatment was necessary to achieve total Tl 234 removal and ensure groundwater security.…”

The Oxidative Precipitation of Thallium at Alkaline pH for Treatment of Mining Influenced Water

“…A number of methods for Tl removal have been reported including: Zn cementation; reductive precipitation; oxidative precipitation; sorption to Mn oxides, organic matter, alumina, and; ion exchange (Bidoglio et al 1993;DOW Chemical Company 2011;Gadde and Laitinen 1974;Jibiki 1995;Memon et al 2008;MWTP 1999;Rissman and Schwartz 1989;Williams-Beam and Twidwell 2003;Zhang et al 2008). However, few methods remove Tl in MIW to less than the EPA MCL of 2 lg/L (MWTP 1999).…”
