[Effect of Preparation Methods on Phosphate Adsorption by Iron-Titanium Binary Oxide: Coprecipitation and Physical Mixing].

To investigate the effect of preparation methods on surface characteristics and adsorption properties of the formed metal composite oxides, two kinds of iron-titanium binary oxides were synthesized by a coprecipitation method or a physical mixing method and were denoted as Fe-Ti and Fe-Ti, respectively. The prepared Fe-Ti and Fe-Ti were systematically characterized using SEM, XRD, BET, and FTIR techniques. Their phosphate adsorption behaviors were also studied via batch adsorption experiments.

[Fe-Mn Binary Oxide Impregnated Chitosan Bead (FMCB): An Environmental Friendly Sorbent for Phosphate Removal].

Fe-Mn binary oxide impregnated chitosan bead (FMCB), an environmental friendly sorbent for phosphate removal, was fabricated through impregnating Fe-Mn binary oxide into chitosan matrix. The FMCB was characterized by SEM and BET surface area measurement. The adsorption behavior of phosphate on the FMCB was systemically investigated.

[Adsorption of Cu on Core-shell Structured Magnetic Particles: Relationship Between Adsorption Performance and Surface Properties].

In order to reveal the relationship between the adsorption performance of adsorbents and their compositions, structure, and surface properties, the core-shell structured Fe₃O₄/MnO2 and Fe-Mn/Mn₂2 magnetic particles were systematically characterized using multiple techniques and their Cu adsorption behaviors as well as mechanism were also investigated in details. It was found that both Fe₃O4 and Fe-Mn had spinel structure and no obvious crystalline phase change was observed after coating with MnO₂. The introduction of Mn might improve the affinity between the core and the shell, and therefore enhanced the amount and distribution uniformity of the MnO₂ coated.

[Preparation and evaluation of Fe-La composite oxide nanoadsorbent for As(III) removal from aqueous solutions].

In this study, a Fe-La composite oxide nanoadsorbent was synthesized via a facile co-precipitation process. This adsorbent was well characterized with various techniques and its As (III) adsorption performance was investigated. Scanning electron microscopy (SEM) and transmission electron microscope (TEM) analyses indicate that the Fe-La composite oxide is formed with nanoparticles (20-200 nm).

[Experiment study on the metamorphic amylum production wastewater treatment by anaerobic baffled reactor].

The present study reports the start-up of treating metamorphic amylum production wastewater by anaerobic baffled reactor (ABR) and the bio-chemical features of granular sludge. The optimal conditions in treatment of the metamorphic amylum production wastewater were proposed, and the running performance in treating salt-containing wastewater was studied. Our results show that the common anaerobic activated sludge can be acclimated by increasing the organic loading and salt-concentration at the same time, and the granular sludge tolerant to low salt can be achieved by the acclimation.

Removal mechanism of As(III) by a novel Fe-Mn binary oxide adsorbent: oxidation and sorption.

A novel Fe-Mn binary oxide adsorbent was developed for effective As(III) removal, which is more difficult to remove from drinking water and much more toxic to humans than As(V). The synthetic adsorbent showed a significantly higher As(III) uptake than As(V). The mechanism study is therefore necessary for interpreting such result and understanding the As(III) removal process.

Plant community succession in modern Yellow River Delta, China.

Data were collected in different successional stages using a simultaneous sampling method and analyzed through quantitative classification method. Three large groups and 12 classes were made to represent the community patterns of three succession stages and 12 succession communities. The succession series of plant community in the study area was as follows: saline bare land-->community Suaeda salsa-->community Tamarix chinensis-->grassland.
