this study illustrates the process of removal of chromium from chrome tanning waste-water by fly ash which was drive from chrome shaving dust. this experiment was carried out in a batch process with laboratory prepared adsorbent samples and chrome tanning water collected from local tanneries. the influence of various factors likes adsorbent doses, contact time, and initial concentration of chro...

Abstract The vaporization of vanadium pentoxide from CaO-SiO 2 -VO x ternary slags using different gas treatment regimens and parallel vacuum extirpation to treat V-bearing at 1873 K has been developed in the present study. novelty study is monitor effect alumina dissolution on phenomenon. Vanadium high vapor pressure temperatures over 1500 K. When slags, kept dense crucibles, are injected with...

the karnafully is one of the most important rivers due to its profound influence on water chemistry and sediment characteristics. the present study intended to assess the quality of water and sediment from intertidal zone of this river in respect to the pollution index. seasonal water and sediment samples were collected during four seasons (monsoon, post-monsoon, winter, and pre-monsoon) of 201...
