| STUDY ON NOVEL SORBENT FOR REMOVAL OF UREA COMPLEX SORPTION OF UREA BY MEANS OF ALGINATE—Cu（Ⅱ） COMPLEX | |
| 摘 要： | Alginate-Cu(Ⅱ）complex beads or membranes were prepared for removal of urea.The mechanism of sorption of urea was identified by UV-Visible spectra,FT-IR spectra and Far-Infrared spectra.The factors affecting the urea sorption capacity were discussed in detail.Results showed that the Alginate-Cu(Ⅱ）complex sorbent can sorb about 60 my urea per gram of sorbent at 37℃ and the concentration of urea was 130mg/100ml in Na2HPO4 and NaH2PO4 buffer solution(pH=7.0). |
