Abstract
The removable of methylene blue (MB) from aqueous solution by the calcined-Kamerotar bulk clay with & without grinding was studied using Langmuir as well as Freundlich adsorption isotherms at room temperature (301±1 K). The bulk clay sample was collected from the Kamerotar area of Madhyapur Thimi municipality of Bhaktapur, Nepal and was used in the present study composed of vermiculite & muscovite type mica minerals in additions of feldspars and quartz with considerable amounts of iron as well as magnesium oxides. The removable capacity of the MB by the calcined-bulk clay sample at 573 K calcination temperature with and without dry grinding was interpreted using Langmuir and Fruendlich isotherms. The maximum removal efficiency of the MB by the clay sample was observed at pH 7-12. The removable capacity of the calcined-clay sample was increased with dry grinding for 2 hours. The maximum amounts of the MB removed by the modified clay sample using the calcination temperature of 573 K are in the ranges of 15.8-19.5 m mole/g. Present study showed that the dry grinded the calcined-
