Activated ivhu ndeye adsorbent yakagadzirwa kubva kuvhu (kunyanya bentonite) seyakabikwa, inobatwa neinorganic acidification, munyu kana dzimwe nzira, yozosukuzwa nekuomeswa nemvura.Iyo ine mukaka chena yehupfu inotaridzika, haina hwema, haina hwema, haina chepfu, uye ine yakasimba adsorption performance.Inogona adsorb mavara uye organic zvinhu.Zviri nyore kutora hunyoro mumhepo, uye kuiisa kwenguva yakareba kunoderedza adsorption performance.Paunenge uchishandisa, zvinokurudzirwa kupisa (zvichida pa80-100 madhigirii Celsius) kumutsidzira.Nekudaro, kupisa kuri pamusoro pe300 madhigirii Celsius kunotanga kurasikirwa nemvura inopenya, zvichikonzera shanduko yezvimiro uye kukanganisa mhedzisiro.Ivhu rakabatidzwa harinyungudike mumvura, organic solvents, nemafuta akasiyana siyana, anenge akanyatso kunyungudika mune inopisa caustic pasoda uye hydrochloric acid, ine hama density ye2.3-2.5, uye kushoma kuzvimba mumvura nemafuta.

Ivhu chena rinongo itika rine machenera evhu ivhu chena, jena grey ivhu rinonyanya kuumbwa ne montmorillonite, albite, uye quartz, uye imhando ye bentonite.

Kunyanya chigadzirwa chekuparara kwegirazi matombo emakomo, asingawedzere mushure mekutora mvura, uye pH kukosha kwekusimisa kwakasiyana neiyo alkaline bentonite;Kuita kwayo kuchena kwakaipa kupfuura kwevhu rakagadzirwa.Mavara acho anowanzo sanganisira yero yero, girini jena, grey, ruvara rweolive, brown, mukaka chena, pichisi tsvuku, bhuruu, nezvimwewo. Kune mashoma mashoma machena.Density 2.7-2.9g/cm.Iyo inooneka density inowanzove yakaderera nekuda kwe porosity yayo.Mushonga wekemikari wakafanana nevhuwo zvaro, rine makemikari makuru ealuminium oxide, silicon dioxide, mvura, uye shoma shoma yesimbi, magnesium, calcium, nezvimwewo. Hapana plasticity, ine high adsorption capacity.Nekuda kwehuwandu hwehuwandu hwe hydrous silicic acid, ine acidic kune litmus.Mvura inowanzoputika uye ine mvura yakawanda.Kazhinji, kutsetseka kwacho, ndiko kuwedzera kwesimba re decolorization.

Paunenge uchiitisa kuongororwa kwemhando panguva yekuongorora, zvinodikanwa kuyera kuita kwayo kuchena, acidity, kusefa kuita, kunyura kwemafuta, uye zvimwe zvinhu.
