Abstract: Rice-husk ash (RHA) was found to be a good adsorbent for Hg(II) in aqueous solutions. Batch studies indicated that the percent adsorption decreased with increasing initial concentration of Hg(II) and particle size of ...

Abstract: The cost and time involved in frequent field observations pertaining to quantification of nitrate leaching below the crop root zone leads to the use of simulation models, which is a more plausible approach. Nitrate leaching ...
