Red soil in southern hill region is an adsorbent with the characteristics of economy, accessibility and so on. The phosphorus adsorption characteristics of red soil were studied in this paper. Differences in parameters of phosphorus absorption at different concentrations with different weights of red soil were compared, and the influence of temperature and pH on the phosphorus adsorption was discussed...
Spherical LiNi0.7Co0.15Mn0.15O2 powders with phase-pure and well-ordered layered structure were successfully synthesized by firing spherical Ni0.7Co0.15Mn0.15(OH)2 precursor and LiOH??H2O in oxygen. The structure, morphology and electrochemical properties of LiNi0.7Co0.15Mn0.15O2 calcined at different temperatures were studied. The average particles size of the powders was about 8-10??m and the size...
The authors derived the normalized difference vegetation index (NDVI) from the NOAA/AVHRR Land dataset, at a spatial resolution of 8km and 15-day intervals, to investigate the vegetation variations in China during the period from 1982 to 2001. Then, GIS is used to examine the relationship between precipitation and the Normalized Difference Vegetation Index (NDVI) in China, and the value of NDVI is...
