Fig. 1. Effects of (A) initial pH of test TCs solution, (B) inorganic ions (CO32−, HCO3−, NO3−, SO42−, and NH4+) and DOMs, on the degradation rate constant (K) of oxytetracycline (OTC), tetracycline (TC), chlorotetracycline (CTC), and doxycycline (DXC) by UV (253....
Another solution of Fe (NO3)3·9H2O (0.1 M), Co (NO3)21·6H2O (0.1 M), Cd (NO3)2·4H2O (0.1 M), and 2.5 g PbI2 was prepared. This later solution was stirred for 24 h. A pH 10 of the reaction is adjusted by using the sodium hydroxide solution. After reaching pH 10, the...
The respective metal salts [(NH4)2Fe(SO4)2·6H2O (0.392 g, 1 mmol), CoCl2·6H2O (0.237 g, 1 mmol), Zn(NO3)2·6H2O (0.189 g, 1 mmol)] were added to the ligand solution (metal: ligand, 1:1) immediately resulting in a turbid solution that was refluxed in an...
The presence of O2 in the solution appears to have an inhibitive effect on the reduction process, especially in the presence of Ni81Fe19 alloy (Tab. 1, runs 56, 58; Fig. 5b). Low temperature experiments (22°C) further confirmed the temperature dependence of NO2-/NO3- reduction in the...

* 在铁系元素中,只有铁能形成稳定的氧化值为+3的简单盐,常见Fe(Ⅲ)的强酸盐,如Fe(NO3)3·6H2O、FeCl3·6H2O、Fe2(SO4)3·12H2O等都易溶于水,在这些盐的晶体中含有[Fe(H2O)6]3+,这种水合离子也存在于强酸性(pH=0左右)溶液中。 由于Fe(OH)3比Fe(OH)2的碱性更弱,所以Fe(Ⅲ)盐较Fe(Ⅱ)盐易...
2. Both types of crystals,grown with the different shapes, were recognizedSince Fe(NO3)3 . 9H~O was used as the starting to be hexatitanate, K2Ti6O~3, containing a fewmaterial, it was reduced to paste at about 50° C. amount of Fe ions. The aspect ratio was beyondSimultaneously, ...
The results showed that the adjust of pH can be used to control the crystal structure and color of FeOOH particles, and the change of oxygen rate, stirring rate, additives and reaction temperature can be used to adjust the particle size and distribution of FeOOH particles. 展开 关键词: ...
α-Fe2O3 and FeMnO3/α-Fe2O3 fibers were successfully prepared via Solution Blow Spinning (SBS). The effect of drying during the SBS process on fiber morphology was evaluated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N2 adsorption–desorption isotherms....
As a solution to the above primary challenges, considerable attention has been paid to the exploitation of renewable resources [1]. In this context, the conversion of the cellulose fraction of biomass into value-added platform chemicals, such as 5-hydroxymethylfurfural (5-HMF) and levulinic acid...
