Rice husk ash and nata de coco are used as the sources of silica and cellulose, both materials can be combined to form a silica-cellulose hybrid. This material can be used as the adsorbent for natural pigment or metals also for any bigger molecule like enzyme. Curcumin and chlorophyll were chosen as the probe adsorbate. This research aimed to know the characteristic of the silica-cellulose hybrid and the adsorption behavior of chlorophyll and curcumin pigments via the batch method and also as a stationary phase in TLC. FT-IR and UV-Vis analysis were involved. The research was an experimental laboratory and divided into 4 steps (1) preparation and produce silica-cellulose hybrid, (2) characterization of silica-cellulose hybrid, (3) application of the material to chlorophyll, curcumin and the mixtures, (4) analysis of surface interaction using spectrophotometer FT IR and UV-Vis. The results of this research showed the role of cellulose in changing the surface properties towards molecular interaction from both batch and thin layer experiments. © Published under licence by IOP Publishing Ltd.
