Abstract
Algae-silica hybrid (HA-S) from Porphyridiumsp. has been modified by coating particles of magnetite (Fe3O4)via a sol-gel process using (TEOS) to produce silica-magnetitealgae hybrid (HA-SM). The produced material HA-SMwasapplied as adsorbent for the multicomponent solution adsorptionof Cu(II) ions, crystal violet (CV), andmethylene blue (MB). Identification of functional groups was performed by infrared spectrometer (IR) indicating that in HA-SM there arean active organic groups derived from Porphyridiumsp.,while silanol and siloxane derived from silica matrix. In addition, the results of the analysis using Scanning Electron Microscopy withEnergy Dispersive X-Ray (SEM-EDX) showed HA-SM has more heterogeneous surface morphology. The adsorption model of the multicomponent solutions ofCu(II) ions, CV, and MB by HA-S and HA-SM tend to followthe model of Freundlich adsorption isotherm.
