7 ACTA CHIMICA SINICA Vol. 75, No. 6 June 15, 2017 Contents On the cover: A nanostructure-based mechanism of encapsulation is presented on the enrichment, separation and immobilization of selenium and arsenic with zero-valent iron nanoparticles. Experimental results demonstrates the rapid separation, large capacity, stability and unique properties of iron nanoparticles for treatment and remediation of toxic heavy metals such as selenium, chromium, arsenic, uranium etc. [Ling, Lan et al. on page ] On the back cover: Fe(II)-catalyzed phase transformation of iron (hydr)oxides is the important chemical reaction of iron cycle in anaerobic environments, such as paddy soils. Through electron transfer and Fe atom exchange reaction mechanisms, ferrihydrite was transformed to lepidocrocite, goethite, and magnetite when catalyzed by Fe(II). With coexisted Pb(II), the phase transformation of ferrihydrite was inhibited and the transformed products were changed due to the competitive adsorption of Pb(II) with Fe(II) on the ferrihydrite surface, while Pb(II) was stabilized in the structures of transformed iron (hydr)oxides.

10 Content Article Removal of Arsenic and Selenium with Nanoscale Zero-Valent Iron (nzvi) Xia, Xuefen; Hua, Yilong; Huang, Xiaoyue; Ling, Lan*; Zhang, Weixian* Acta Chim. Sinica 2017, 75(6), Nanoscale zero-valent iron (nzvi) has a remarkable capability to remove As and Se from aqueous solutions. The removal performances of nzvi for As(III), As(V), Se(IV) and Se(VI) were different due to the different reaction mechanisms. Arsenic (As(III/V)) can be removed by the synergistic effects of adsorption, reduction and co-precipitation. Meanwhile, aqueous Se(IV/VI) was first immobilized by adsorption, and then reduced to Se(0)/Se(-II). Especially, pure Se(0) nanostructures could be generated under ambient temperature and pressure. Copper Ions Promoted Aerobic Atrazine Degradation by Fe@Fe 2 O 3 Nanowires Jia, Falong; Liu, Juan; Zhang, Lizhi* Acta Chim. Sinica 2017, 75(6), The addition of Cu 2+ could enhance the rate of aerobic atrazine degradation with Fe@Fe 2 O 3 nanowires because of the efficient release of Fe 2+ ions and the molecular oxygen activation. Influences and Mechanisms of As(V) Concentration and Environmental Factors on Hydrosulfate Green Rust Transformation Wang, Xiaoming; Peng, Jing; Xu, Huanhuan; Tan, Wenfeng; Liu, Fan; Huang, Qiaoyun; Feng, Xionghan* Acta Chim. Sinica 2017, 75(6), With increasing As(V) concentration, the transformation products of GR2(SO 4 2 ) change from mixed phases of goethite and lepidocrocite to pure lepidocrocite to mixed phases of lepidocrocite, ferrihydrite, and ferric GR2(SO 4 2 ). When Fe/As molar ratio is 24, lepidocrocite is the main product at the conditions of ph 6.59, temperature of 5 45, and air rate of m 3 /h. High ph and air rate, and low temperature favor the formation of ferrihydrite and ferric GR2(SO 4 2) Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences Acta Chim. Sinica 2017, 75,

Adsorption and Stabilization of Lead during Fe(II)-catalyzed Phase Transformation of Ferrihydrite Liu, Chengshuai; Li, Fangbai*; Chen, Manjia; Liao, Changzhong; Tong, Hui; Hua, Jian Acta Chim. Sinica 2017, 75(6), With the coexisting Pb(II), Fe(II)-catalyzed phase transformation of ferrihydrite was inhibited due to the competitive adsorption of Pb(II) with Fe(II) on the surface of ferrihydrite. Through electron transfer and Fe atom exchange reaction mechanisms, ferrihydrite was transformed to lepidocrocite, goethite, and magnetite catalyzed by Fe(II), in which Pb(II) was stabilized in the structures of these transformed iron (hydr)oxides.

Sinica 2017, 75(6), The adsorbed HA coated on the surface of BC@Ni/Fe occupied the active sites, which hindered the nanoparticles to contact with H 2 O, reduced the corrosion of Fe 0, thus inhibited the removal of BDE209. The Acid-Base Buffer Capacity of Red Soil Variable Charge Minerals and Its Surface Complexation Model Cheng, Pengfei; Wang, Ying; Cheng, Kuan; Li, Fangbai; Qin, Haoli; Liu, Tongxu* Acta Chim. Sinica 2017, 75(6), The acid-base property parameters of variable charge minerals were obtained by Gran plots with the 1-site/2-pK surface complexation model. These parameters, including their surface active sites concentration (H s ) and density (D s ), their acid-base equilibrium constants (pk a int ) and the charge zero ph pzc, can reflect the acid-base buffer capacity of the soil minerals and further be used to predict the speciation distribution of red soil minerals under different ph.
