Teff straw, a by-product of Teff, mainly available in Ethiopia, has not been studied much for biosorbent production. The present study investigated the effects modification and optimization process parameters (viz., concentration modifying agent (H3PO4 KOH), temperature, time) on Cr (VI) removal efficiency using chemically activated straw by RSM followed BBD. maximum was obtained an H3PO4-modif...

Cassava peel is a natural material that still underutilized even though has the potential as an alternative to activated carbon precursors. In synthesis of carbon, impregnation ratio and activation temperature are important factors affect characteristics produced. This study aims determine effect variations in (carbon: H3PO4) on from cassava (CPAC) optimal conditions manufacture CPAC. this stud...

The effectiveness of Snail Shell as adsorbent for the treatment of wastewater from beverage industries, using Phosphoric acid (H3PO4) as activating agent has been investigated. The snail shells were pyrolysed at 500C and partitioned into two parts; one part as sample A and the other further treated with the activating agent as sample B. The samples were characterized for some important properti...

The corrosion inhibition performance of acetylacetonate complexes of zinc(II), manganese(II), cobalt(II) and copper(II) on the mild steel substrate in 1M H3PO4 was studied using DC polarization. It was seen that the mentioned complexes decreased corrosion rate of mild steel in phosphoric acid media due to the adsorption on metal surface. The potential of mild steel shifted toward more active po...
