Garaafka la balaariyay waa adsorbent aad u wanaagsan, gaar ahaan waxa uu leeyahay qaab-dhismeed dabacsan oo dabacsan oo leh awood adsorption adag oo loogu talagalay xeryahooda organic. 1g ee garaafyada la balaariyay waxay nuugi kartaa 80g oo saliid ah, sidaas darteed graphite balaadhinta waxaa loogu talagalay noocyo kala duwan oo saliid warshadeed ah iyo saliid warshadeed. adsorbent. Tifaftiraha garaafiga Furuite ee soo socda ayaa soo bandhigaya cilmi-baarista ku saabsan xadhkaha galka walxaha saliidda sida saliidda culus iyadoo la adeegsanayo garaafka la ballaariyay:
1. Garaafyada fidsan waxaa loo isticmaalaa nooc cusub oo adsorbent ah sababtoo ah tirada badan ee daloolada dusha falanqaynta.
Gooryaanka graphite balaariyay mesh midba midka kale, samaynta daloolo badan oo dusha sare ah, kaas oo ku haboon in ay adsorption ee walxaha macromolecular, muujinaysaa awood adsorption weyn, kaas oo xalin kara dhibaatada saliidda iyo organic non-polar walxaha.
2. Garaafka fidsan waxaa loo isticmaalaa nooc cusub oo adsorbent ah sababtoo ah mesh weyn oo gudaha ah
Si ka duwan xayaysiisyada qalabka kale, molecules gudaha ee garaafyada la balaariyay ayaa inta badan ah daloolada dhexdhexaadka ah iyo kuwa waaweyn, badankooduna waxay ku jiraan xaalad isku xiran, iyo xiriirka shabakada ee u dhexeeya lamellae ayaa ka fiican. Waxay leedahay saameyn aad u wanaagsan oo ku saabsan xayeysiinta macromolecules organic ee saliiddan culus. Unugyada saliidda culus si fudud ayaa loo heli karaa waxayna si degdeg ah ugu faafaan shabakadooda ilaa ay ka buuxiyaan daloolada gudaha ee isku xiran. Sidaa darteed, saameynta xayeysiinta ee garaafyada la ballaariyay ayaa ka wanaagsan.
Sababo la xiriira qaab-dhismeedka dabacsan iyo dalool ee graphite balaariyay, waxay leeyihiin saamayn adsorption wanaagsan on qaar ka mid ah wasakhowga saliidda iyo wasakhowga gaaska, taas oo ka dhigaysa in si weyn loo isticmaalo berrinkii ilaalinta deegaanka.
