of initial concentration of metal ions on adsorption 图4 温度对羊栖菜吸附Cu2+ 的影响 Fig. 4 Effect of temperature on biosorption of Cu2+ by S.fusiforme 2.1.5 离子强度 2.1.5.1 干扰离子 图5表明,吸附液中存在Na+,Ca2... of Cd2+ is 92.54% under condition of the optimum adsorption pH 5, the temperature 313.15 K, the concentration of adsorbent 1 g/L and the initial concentration of Cd2+ about 40 mg/L, and when......
the melt in the form of Al8Mn5 phases, and then the little Al8Mn5 phases enter into the dendritic with the α-Mg primary crystals growing up with temperature decreasing. At the same time, Al and Zn enrich......
with boric acid show that the calcining temperature decreases and the average particle size obviously increases. The intensities of exciting spectra and emitting spectra markedly enhance, the emitting......
. A great quantity of β phase is retained when cooling to low temperature. This less-stabilized retained β phase tends to undergo transformation to coarsener second α′ phase with increasing heat input......
: The lotus-type porous copper bars with 45 mm in diameter and 120 mm in length were fabricated by unidirectional solidification at hydrogen pressure of 0.2 MPa and molten temperature of 1 200......
1.0%; temperature 680 ℃; stirring time 1.5 min; holding time 2.5 min). The average pore diameter is uniform and below 1.5 mm. The wetting behaviors are the main factor of influencing the pore diameter......
of the molar ratios of K2CO3 to TiO2 of H2TiO3 (n(K2CO3)/n(TiO2)), calcination temperature, and calcination time on the crystallinity and the morphology of the resultant potassium titanate were investigated......
solid solution, over-aging, heavy strain by combination of multi-directional forging and rolling at warm temperature and re-crystallization by fast heating was proposed and studied for structure......
temperature, nitrogen and (Co, N) codoped TiO2 sols were obtained. Various thin film electrodes were prepared from the sols using dip-coating approach. These films were characterized by XRD, SEM, XPS, UV......
of Technology, Lanzhou 73005, China) Abstract: 350, 400, 475 and 600 K below glass transition temperature were chosen for isothermal annealing for 1 h. Mechanical properties and deformation of Cu... metallic glasses[J]. Journal of Alloys and Compounds, 2007, 441(1/2): 62?65. [14] Jiang Q K, Nie X P, Jiang J Z, et al.
