Kaarboon firfircoon ayaa laga soo saaray badeeco qashinka noolaha ah, balka alwaax ah (RWSD) iyadoo la isticmaalayo uumi ku jira dab-kiciye sariireed heerkul sarreeya.Tijaabooyin ayaa la sameeyay si loo baaro saameynta cabbirrada nidaamka kala duwan sida waqtiga firfircoonida, heerkulka firfircoonida, cabbirka walxaha iyo xawaaraha dareeraha ee tayada kaarboonka firfircoon.Kaarboonka firfircoon ayaa lagu sifeeyay iyadoo lagu salaynayo nambarkiisa iodine, lambarka buluuga ah ee methylene, Brauner Emmet Teller (BET) oogada sare iyo bedka dusha sare ee la helay iyadoo la adeegsanayo habka haynta ethylene glycol mono ethyl ether (EGME).Kaarboonka firfircoon ee ugu tayada wanaagsan waxaa la helay waqtiga firfircoonida iyo heerkulka 1h iyo 750 C celcelis ahaan cabbirka walxaha 0.46 mm.Kinetics-ka xayeysiinta waxay muujineysaa in heerka-dalbalka-labaad ee been-abuurka ah uu ku habboon yahay kinetics-ka xayeysiinta si ka wanaagsan isla'egyada heerka-dalabka-ka-hortagga ah ee been-abuurka ah.Awoodda adsorption ee kaarboon laga soo saaray RWSD ayaa la ogaaday inay tahay 1250 mg g(-1) dheeha Bismark Brown.Qiimaha joogtada ah iyo isugeynta isticmaalka kala duwan ee gaadiidka intraparticle ayaa lagu go'aamiyay kaarboonka firfircoon ee uumiga.Sifada kaarboonka firfircoon ee la diyaariyey ayaa la helay marka loo eego kaarboonka firfircoon ee ganacsiga.
