This paper deals with calcium and magnesium ion leaching by acid rain from typical soils of the area. Laboratory experiments were conducted on soil monoliths (15 cm in diameter, 50 cm high) with acid solutions of pH 3.0, pH 2.0 and a water control of pH 5.6. The sprinkling lasted 30 ...
Simulated acid rain with pH 2.0 caused visible direct damage to the leaves of Toona sinensis. Yellow-white speckles appeared on the edges of the leaves and between the venations,and some leaves were even perforated. Visible damage was not observed on other trees. The results show that the pH...

Northern China had a higher concentration of acidic ions in the precipitation than that in the south, but the pH of precipitation was almost higher than the threshold value of acid rain (pH = 5.6) in Northern China, because there were enough alkaline substances (e.g., alkaline particles and...

The anoxic zone enables a biofilm reactor to be more tolerant than floc reactors to environmental shocks such as changes to dissolved oxygen (DO), salinity and pH (Luo et al., 2014; Zhu et al., 2015). In addition, because of the bidirectional penetration of substances (external nitrate ...
而且SO2的连续溶解还导致使薄液膜PH值降低, 这进一步加速Mg的溶解, 形成了稳定的腐蚀产物Mg2SO4。 高强AZ80镁合金暴露在青岛海洋大气环境中, 海洋环境中SO4 2-、Cl-会沉积在样品表面(图6)。由于SO4 2-、Cl-的吸湿性很强, 会在镁合金表面形成一层薄液膜, 因此镁合金的海洋大气腐蚀过程, 就是表面薄液膜中的...
