Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 3,   Pages 545-553 doi: 10.1007/s11783-014-0657-x

Abstract: A novel environmentally friendly type of calcium carbonate, zinc (II) and iron (III) scale inhibitor Acrylic acid- allylpolyethoxy carboxylate copolymer (AA-APEL) was synthesized. The anti-scale property of the AA-APEL toward CaCO , zinc (II) and iron (III) in the artificial cooling water was studied through static scale inhibition tests. The observation shows that both calcium carbonate, zinc (II) and iron (III) inhibition increase with increasing the dosage of AA-APEL. The effect on formation of CaCO was investigated with combination of scanning electronic microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD) analysis and fourier transform infrared spectrometer, respectively. The results showed that the AA-APEL copolymer not only influenced calcium carbonate crystal morphology and crystal size but also the crystallinity. The crystallization of CaCO in the absence of inhibitor was rhombohedral calcite crystal, whereas a mixture of calcite with vaterite crystals was found in the presence of the AA-APEL copolymer. Inhibition mechanism is proposed that the interactions between calcium or iron ions and polyethylene glycol (PEG) are the fundamental impetus to restrain the formation of the scale in cooling water systems.

Management strategies of marine food resources under multiple stressors with particular reference of the Yellow

Qisheng TANG

Frontiers of Agricultural Science and Engineering 2014, Volume 1, Issue 1,   Pages 85-90 doi: 10.15302/J-FASE-2014021

Abstract:

In this study two main management strategies are discussed: one is to develop resource conservation-based capture fisheries, and the other is to develop environmentally friendly aquaculture. During the resource recovery period, the development of environmentally friendly aquaculture should be encouraged, especially in integrated multi-trophic aquaculture, which is adaptive, efficient and sustainable. For future development and better understanding the ecosystem, it is necessary to further strengthen basic research.

Phosphorous removal from wastewater by lanthanum modified Y zeolites

Weikang ZHANG, Ye TIAN

Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 2,   Pages 209-215 doi: 10.1007/s11705-014-1448-4

Abstract: The adsorption capacities of Y zeolite and La (III)-modified Y zeolite were studied. A series of La(III)-modified Y zeolites with different La/Y zeolite mass ratios were characterized by X-ray diffraction, X-ray fluorescence and Brunauer-Emmett-Teller surface area analysis. Batch experiments were conducted to evaluate the effects of various experimental parameters, such as pH, ionic strength, coexisting anions ( , Cl , and ) and temperature, on the phosphate adsorption. The capacity of the La (III)-modified Y zeolite to remove phosphate increased as the La/Y zeolite mass ratio increased and after 4 h, a phosphate removal efficiency of 95% was achieved for a La/Y zeolite mass ratio of 0.10. The equilibrium adsorption isotherm data correlated better to the Langmuir model than the Freundlich model and the data followed a pseudo-second-order kinetic equation.
