In addition,it was observed that there were viscosity enhancement phenomena in the saline solution of the terpolymers,in which the ionic strength of NaCl or CaCl_2 was 1.26×10~(-3)~4.88×10~(-3) mol/kg or 1.07×10~(-4)~5.28×10~(-4) mol/kg,respectively.
In the saline solution 〔ρ(NaCl)=2~10 (g/dL),ρ(CaCl_2)=0.2~1.0 g/dL〕 of hydrophobically associated terpolymers,there appears viscosity enhancement phenomena.
A systematic investigation was performed on the influence of several factors such as ageing of the reaction mixture, alkalinity, salt addition and temperature on the formation of a mordenite membrane on the seeded support.
With increasing the amount of salt, there was hardly influence on the growth rate along c-axis, whereas an obvious decline was observed in the growth rate along either a-axis or b-axis, which enlarges the boundaries between the surface crystals.
Three kinds of bis-quaternary ammonium salts of peroxotungstate and peroxomolybdate, such as PhCH2N-(CH2)6NCH2Ph[W(O2)4] · 2H2O, PhCH2N(CH2)6NCH2Ph[W-O(O2)2(C2O4)] and PhCH2N(CH2)6NCH2Ph[MoO(O2)2(C2O4)], have been synthesized and characterized.
The macromolecular impurities, such as nucleic acids, polysaccharides and proteins, were precipitated, and inorganic and organic salts were crystallized.
euphratica leaves exhibited a higher capacity to exclude salt in a longer period of increasing salinity, thus limited salt-induced lipid peroxide and MP, which contributed to membrane integrity maintenance and salt tolerance of P.
The results of seed germination under various environmental stresses and investigation of soil conditions indicate that well-aerated, slightly acidic soils with low salinity are suitable for the growth of S.
The results showed that the zooplankton in the Yueqing Bay could be divided into four ecotypes, namely coastal low saline species, estuary brackish water species, offshore warm water species, and eurytopic species.
The coastal low saline species was the dominant ecotype in the study area, and the dominant species were Labidocera euchaeta, Acartia pacifica, Acrocalanus gibber, Pseudeuphausia sinica, and Sagitta bedoti among others.
It is important to characterize the hydraulic properties of this reclaimed land to be able to predict and manage salt and water movement for amelioration of these saline soils.
Peroxidation reactions were carried out in buffered physiological saline (BPS) supplemented with 2% dimethylsulfoxide (DMSO), pH 7.4 (medium A), or in 40% aqueous dimethylformamide (DMF), pH 7.4 (medium B).
