(dimethylformamide), and then characterized by FTIR, XPS and sedimentation experiments. Results showed that alkanes were successfully linked onto the PANI-SSA chains. The compatibility between N-alkylated PANI-SSA......
at-0.5 V,and Y3+ could be deposited at-0.7 V on tungsten electrode compared with platinum electrode.The sedimentation of Mg2+ was more positive about 230 mV than that of other ions in electrolyte.The......
settlement and continual slurry preparation without hardening in vertical sand silo were eventually realized by the addition of an effective flocculating agent (NPA). The results show that the sedimentation velocity of interface between unclassified tailings and water after the addition of NPA increases by 10-20 times, the sedimentation mass fraction of unclassified tailings at the bottom of vertical sand......
堆体的渗透性和提高浸出率,具有重要的意义. 关键词:微粒；渗滤沉积；排土场；渗流特性；数学模型 中图分类号:TD 853.87 文献标识码:A Effect of particles sedimentation during leaching on seepage characteristic of copper... Engineering, University of Science and Technology Beijing, Beijing 100083, China) Abstract: Based on the effect of particles sedimentation during leaching on the seepage characteristic of copper dumps......
and polycyclic aromatic hydrocarbon (PAH) content in the sludge from sedimentation and filter of drinking water treatment plant in Nanjing were studied. According to Udden-Wentworth standard, the sludge particles can be divided into four fractions: ＜3.9 μm, 3.9-63 μm, 63-250 μm and ＞250 μm. The size fraction of 3.9-63 μm accounts for 55% and 73% (volume fraction) of sludge from sedimentation......
steeply and the faults strike in NW with the small fractures. Fault evolution mainly experienced 3 different deformations: extensional deformation during the sedimentation of the Qingshankou formation (Ⅰ), sustainable extensional deformation during the sedimentation of K1n1 and K1n2 (Ⅱ), and reversal deformation during the sedimentation of the K1n3~the quaternary period(Ⅲ). The fractures had an intense......
and bauxite ore were carried out by the sedimentation. The sodium carbonate and an organic flocculant HSPA were used as dispersant and flocculant, respectively. The results show that HSPA has a good selectivity for the flocculation separation of diasporic-bauxite. The concentrate with Al/Si 8.9 and the recovery of Al2O3 86.98% were obtained after triple sedimentation on the bauxite ore with Al/Si 5.68......
distribution of cutting waste were characterized. The Si-rich powders were obtained from the cutting waste using a physical sedimentation process, and then further purified by removing impurity using acid...; recovery; physical sedimentation; high temperature melting 1 Introduction Solar energy becomes one of the most important renewable clean energies in 21st century due to the limitations in conventional energy......
, and the sedimentation of excessive REOF at the bottom. The RE contents in molten salts were used to determine the solubility of RE2 O3. The results show that with 20 mol%-40 mol% of REF3, the solubility......
