Blood clam seashells was calcinated at 800 0C of ±9 hours. Blood clam seashells contained CaO . The aim of this study was to see potential of blood clam seashell ash as absorbent of tin. The research was conducted by contacting was tin ion and blood clam seashell ash with the variation of concentration. Tin analysis performed by using atomic absorption spectroscopy (AAS). The results showed that optimal absorption occurs at 30 mg/L, at 15 hours was 66,53%otherBlood Clam SeashellsAdsorbentTinAtomic Absorption SpectroscopyOther
