In soda activation, soda ash powder was added to the initially moisturized bentonite samples and kneaded till all the bentonite had reacted with soda. After soda addition and kneading, the activated samples were left to drying/curing under sunlight for a month to complete the activation process (Harvey and Lagaly, 2006).

Abstract. Magzoub, et al 20171 have proposed a method of converting calcium bentonite to sodium bentonite. The method will require a reactor for upscaling. The method involves preparation of soda ash solution, heating, mixing for at least 24 hours and finally removing impurities and drying out. Besun et al. 19972 have proposed a method that will …
