Penambahan Template Kitosan dan Albumin pada Sintesis Nanosilika Abu Ketel Industri Gula dengan Metode Kopresipitasi.

Abstract

Nanosilica has many potential application in widely sectors. Boiler ash has contains silica that synthesized using precipitation method. Templating was modification process from precipitation method. The objective of this research was to synthesis nanosilica with template from boiler ash using precipitation method, determine the effect of chitosan and albumin templates on the characterization of nanosilica, determine the potential application based on characterization of nanosilica. This research consist of several stages, preparation of boiler ash, silica extraction, synthesis of nanosilica, testing of material, testing and characterization of nanosilica, and analyze of data. Boiler ash contained 49.69% silica and furnace ash contained 78.75% silica. Increasing concentration of chitosan and albumin templates was decrease amount of diffraction peak, diffraction peak intensity, decrease average of crystal size, narrow of crystal size distribution, and narrow of particle size distribution (PDI) curve. Degree of crystallinity nanosilica with chitosan template has ranges 34.40-54.69% and with albumin template has ranges 39.33-68.79%. Crystal size nanosilica has ranges 35.87-61.57 nm. Particle size nanosilica has ranges 228.39-1369.23 nm. PDI value nanosilica has ranges 0.09-0.297. Nanosilica has potential application as compose top layer of ultrafiltration membrane, compose porous support of ultrafiltration membrane, and support component of catalyst.
