IDENTIFIKASI SISIK IKAN ASIN SEBAGAI SUMBER ADSORBEN UNTUK PENJERAPAN LOGAM Pb

Abstract

Salted fish scale has potential as an adsorbent for Pb metal removal from aqueous solutions under different experimental conditions. This study was designed to evaluate the effect of physical pretreatments and particle size concerning properties of salted fish scaled. Adsorben from salted fish scale prepared with 3 methods, that were washed with water, soaked at room themperature, soaked at themperature of 80oC. The fish scales were allowed to dry in sunshine for 2 days. The scales were then kept in an oven at 105oC. The adsorbent was characterizationed surface area. The result, sample were washed with water has surface area 8.095 m2/g, sample were soaked at room themperature has surface area 11,1 m2/g, sample were soaked at themperature 80oC has surface area 19,83 m2/g. The maximum concentration for adsorption Pb(II) on salted fish scale that washed with water was at 10 ppm which the %adsorption was 28,05%.
