| 1 | Copper Adsorption on Olivine显示文摘Copper adsorption on olivine supplied by the A/S Olivine Production Plant at Aheim in western Norway was studied. The factors were evaluated which affect the uptake of copper. It is shown that the equilibrium pH of aqueous solution has the greatest influence on copper adsorption thanks to the competitive adsorption between proton and copper ions, and the adsorption of copper to olivine increases rapidly with pH increasing from 4 to 6. Moreover, initial copper concentration and olivine dose possess significant effect on copper adsorption, for the adsorption rate of copper increases with olivine dose increasing or initial copper concentration decreasing at the same pH. In addition, the ionic strength effect on the adsorption was also investigated, but it owns little effect on the adsorption process of copper due to the formation of inner sphere adsorption of copper on olivine. The experimental data show that olivine has a high acid buffer capacity and is an effective adsorbent for copper. | Lei Shao, Rolf A. Kleiv, Kunt L.

| 3 | Synthesis of Zeolites by Alkaline Activation of Fly Ash显示文摘In terms of mineral transformation, and chemical composition of acid-soluble component as a function of reaction time, the effect of alkaline solution on zeolite-like fly ash was studied by employing fly ash and NaOH solution as starting materials. When fly ash and 1-10mol/L NaOH solution were processed at 100 ℃ for 24h with 1:10 W/S ratio in a relatively closed system, powder XRD patterns of resulting products indicated the formation of various zeolites. Zeolite P crystallized early at low alkaline concentration, which was replaced then by zeolites X and A. At high concentration, hydroxy sodalite was the only new phase. Quartz, in fly ash and NaOH solution system, gradually dissolved, and mullite, however, remained stable. It was concluded that, with Al/Si and Na/Si finally reaching equilibrium in molar ratio, composition of starting mixtures affects the crystallization of zeolite from fly ash. | Hua wang, Qiang Zhang, Cunyi Song, Fengmei Liu Civil and Environmental Engineering School, University of Science and Technology Beijing, Beijing 100083, China | 2001 | Journal of University of Science and Technology Beijing2001，8，3： | 2 |

| 13 | Corrosion inhibition of low phosphonic multipolymer water treatment agent of industry circulating on brass in aqueous solution显示文摘In response to environmental guidelines, a low phosphonic multipolymer was synthesized and its corrosion inhibition effi-ciency to brass in synthetic water was investigated through weight loss measurements and electrochemical tests. It showed that thesynthesized inhibitor decreased corrosion under the conditions tested. Potentiodynamic polarization curves indicated that the new in-hibitor acted as an anodic inhibitor, reducing metal dissolution. The composition of protective films formed on the brass was studied byenergy-dispersive X-ray analysis (EDX). The inhibition effects were due to the formation of a protective film of the multipolymer in-hibitor on the metal surface. | Chen Wang Li Wang Cunyi Song | 2006 | Journal of University of Science and Technology Beijing2006，13，2： | 0 |
| 14 | Water-affinity of Perlite Products and Its Anti-water Mechanism after Being Modified显示文摘The structure modification and its mechanism have been studied when perlite products changed from water-affinity state to anti-water state. The structure of fused perlite and its surface physicochemical properties have also been studied. The modification of perlite products has provided the products with anti-water property, which not only enhanced the quality of thermal insulating function, reduced the lost of heat energy, but also made the products water-proof These modified perlite products are used as ideal thermal insulating layers for the thermodynamic equipment and heat transporting conducts. | Cunyi Song Wen Ni Deping Chen(Resources Engineering School, University of Science and Technology Beijing, Beijing, 100083, China) | 1999 | International Journal of Minerals,Metallurgy and Materials1999，13，3： | 0 |
| 15 | Enhanced removal of phosphate from water by fabricatinga novel dual metal MIL-101(Fe/Zr)显示文摘Metal-based compounds are promising adsorbents for phosphate.A novel dual metal-organic framework as an effective adsorbent for phosphate was synthesized by a solvothermal method.The structure analysis revealed that the as-prepared adsorbent(denoted as MIL-101(Fe/Zr))possessed a porous polyhedral structure with a large specific surface area of 479.1 m^(2)/g and a pore width of 3.4 nm.The X-ray diffraction pattern and Fourier transform infrared spectra suggested that the MIL-101(Fe/Zr)shared a similar structure with MIL-101(Fe),implying successful incorporation of Zr atoms as a second metal into the MIL-101(Fe)structure.Kinetic adsorption of PO_(4)^(3-)by MIL-101(Fe/Zr)conformed to the pseudo-second-order model and intraparticle diffusion model,while adsorption isotherm fitted the Freundlich model well(R^(2)=0.9785).It is suggested that such an adsorption belonged to multiply-layer adsorption.The adsorption capacity of MIL-101(Fe/Zr)was to be 66.00 mg/g.MIL-101(Fe/Zr)performed well at a wide range of pH 2.0~10.0 and high ionic strength(0~40 mg/L NaCl).A structural analysis indicated that the complexation interaction was mainly responsible for PO_(4)^(3-)adsorption.These findings can inspire preparation of other dual metal MOFs adsorbent for phosphate removal and recovery from water. | JIAO Zhen MIAO Zhijia LI Qing AN Heluan MENG Xiangyuan SONG Cunyi | 2022 | 南水北调与水利科技(中英文)2022，20，3： | 0 |
