Substituting may use more than 5 equivalents in relation to the imidazole nitrogens to be substituted.Type: ApplicationFiled: November 1, 2007Publication date: October 27, 2011Inventors: John R.

Publication number: 20110247981Abstract: This invention provides an adsorbent material capable of effectively trapping a target component in a sample solution and releasing the same, which has the satisfactory trapping capacity via hydrophobic interactions and via ion exchange reactions. The invention relates to an adsorbent material comprising a porous material of a polymer compound which is a copolymer obtained via copolymerization of a hydrophobic monomer (A), a hydrophilic monomer (B) capable of undergoing a second-order reaction, and a hydrophilic monomer (C) exhibiting a hydrogen-bonding capacity, and via introduction of an ion exchange group into a repeat unit derived from the hydrophilic monomer (B).Type: ApplicationFiled: December 11, 2009Publication date: October 13, 2011Inventors: Tetsuyoshi Ono, Yoshinori Inoue

Publication number: 20110226699Abstract: Silica polyamine composites (SPC) made from silanized amorphous nano-porous silica gel and poly(allylamine) (BP-1) were functionalized with phosphorus acid using the Mannich reaction, resulting in a phosphonic acid modified composite (BPAP). Zirconium (IV) was immobilized on BPAP. Arsenate anions strongly adsorbed on the ZrBPAP composite in the pH range 2 to 8, while arsenite only adsorbed well at pH 10. Regeneration of the resin was carried out successfully for As(V) and As(III) using 2M-H2SO4. Four adsorption/desorption cycles were performed for As(V) at pH 4 without significant decrease in the uptake performance. ZrBPAP capture capacity and kinetics for arsenate were tested for longevity over 1000 cycles with only a marginal loss of performance.Type: ApplicationFiled: March 22, 2011Publication date: September 22, 2011Inventors: Edward Rosenberg, Varadharajan Kailasam
