    Abstract

    Ampo is one of nature material that by public benefit as remover bitter taste at papain leaf. Ability of ampo in adsorption of bitter taste of papain leaf indicates that ampo has adequate surface area causing is concluded that ampo potency as adsorbent. Usage of ampo nature directly as adsorbent has constraint that is when staying in water would be brittle and swelling as a result ability of the adsorption not optimal. To increase ability of the adsorption and resilience in water hence done modification ampo with pilarisation method. Pilarisation is done with interkalation polioksokation Fe3+ into between interlayers ampo then is calcination. At research is studied hydrolysis ratio influence OH/Fe { 1 ; 15; 2 ; 25} at Fe/ampo 2 with calcination temperature 400 oC during 4 hour. Product of Fe2O3 pillared ampo will be characterized of physical properties that is basal spacing using X-ray difraction, surface area with surface area analyzer NOVA 2000 using BET method, pore size distribution analysis with two method are De Boer and Modified Horvath Kawazoe, structural morphology with SEM and adsorption capacities methyl violet with Langmuir isotherm model. Result of research indicates that pilarisation can increase surface area for ratio OH/Fe [ 1= 19.68; 15= 38.86; 2 = 65.53 and 2.5 = 57.67] m2/g, surfacea area ampo 34.0273 m2/g. At comparison [ OH/Fe = 2] shows higher value from all variables with basal spacing 15.79 oA, surface area 99.5618 m2/g, pore diameter 4.815 oA and total pore volume 61.02 cc/g. Structural morphology from SEM indicates that surface structure pillared ampo to be more porous than ampo without pillar. Keywords: Ampo, Pillared ampo, pillarization, hydrolisise.
