This work deals with geopolymers based on local Jordanian resources namely kaolin and zeoltitic phillipsite tuff The geopolymers were prepared from these two materials by a reaction with an alkali solution at 80oC The research group of the present work has demonstrated in previous work that addition of zeolitic tuff to kaolin basedgeopolymers increases the adsorption capacity toward CuView Detail
The leaching of CuII PbII and CrIII obtained for kaolinzeolite geopolymer in the present work is lower than most of those reported for metakaolin and fly ash based geopolymers Table 3 Reported literature values of the leaching of some metals from different geopolymer matricesView Detail
Fig 2 shows the residual concentrations of PbII as a function of reaction time for batch serum tubes containing 01 g of KnZVI and kaolin in the absence of loaded nZVI shown in the insert figure and 10 mL of different initial concentrations of 500 2500 5000 and 10000 mg L −1 PbII The results demonstrate that the equilibrium for PbII removal from solution was reached withinView Detail
