Optimasi Waktu Dan Massa Ca(Oh)2 Pada Proses Recovery Naoh Dari Na2co3 Produk…

ABSTRACT Sodium hydroxide is one of the basic chemicals that has an important role in the production process such as silica. NaOH is used as a solvent to dissolve the silica present in the palm fly ash. NaOH recovery is an alternative to reduce production costs. This study aims to determine the NaOH recovery process in the manufacture of silica from palm fly ash. NaOH is recovered using th…
