The average content of H2O-Pi, NaHCO3-Pi, NaOH-Pi, HCl-Pi, NaHCO3-Po, NaOH-Po and Residual-P pools were 10.8, 46.8, 115.6, 218.6, 22.3, 104.9 and 193.8 mg·kg-1, respectively. With an increase in soil available phosphorus levels, the contents of NaHCO3-Pi and NaOH-Pi increased significantly, and the stable phosphorus pools (HCl-Pi and Residual-P) were relatively stable.

The GWI values of lignites range from 0.47 to 2.03 (except for one higher value 18.13, could be due to mineral matter influx and/or intermittent marine influence), and the VI values range from 0.39 to 1.99 suggesting a good, but fluctuating (mesotrophic to rheotrophic), hydrological condition (ground-water level) was prevailing during the ...

Pitting corrosion

Pitting corrosion is a form of localized corrosion, which produces attacks in the form of spots or pits. Pitting corrosion may occur in stainless steels in neutral or acid solutions containing halides*, primarily chlorides (Cl - ), such as seawater. Pitting corrosion attacks most often take place at points where the passive layer might be ...
