Abstract

Invenþia se referã la procedeele de obþinere a adsorbantului, în special a cãrbunelui activ.Esenþa invenþiei constã în aceea cã se propune un procedeu de obþinere a adsorbantului, care include pregãtirea amestecului de coajã de sâmburi de fructe ºi nuci cu tescovinã de floarea- soarelui în cantitate de 10…15% mas., fãrâmiþarea lui ºi tratarea cu soluþie acetatã de 10…20% a sãrurilor de bariu, fier(II) ºi fier(III) în proporþie molarã 1:2:4 timp de 96 ore, apoi cu soluþie de bicarbonat de potasiu, separarea de soluþie, carbonizarea ºi activarea la temperatura de 480…550°C în regim izotermic timp de 2…3 ore.Rezultatul constã în obþinerea cãrbunelui activ cu porozitate ºi proprietãþi feromagnetice sporite.
