Abstract
Zeolit alam adalah adsorben yang selektif. Untuk mengetahui selektifitas adsorpsi zeolit alam terhadap Co2+ dan Ni2+ maka perlu penetapan konstanta adsorpsinya. Metode yang dipakai adalah dengan memvariasikan konsentrasi awal Co2+, Ni2+, campuran Co2+ dengan Ni2+ yang diadsorpsi. Variabel bebas konsentrasi awal.dan varabel yang dikon.stankan massa dan jenis zeolit jenis dan massa zeolit, pH, Temperatur dan pelarut. Dan penelitian yang telah dilakukan di dapatkan hasil sebagai berikut : Konstanta adsorpsi Co2+ 1762,027 L mal '1, luas permukaan maksimal yang dapat tertutup oleh Co2+ 2,21 x 104 mot Log 1. Konstanta adsorpsi Ni2+ tidak teramati. Kesimpulan dari penelitian ini adalah : zeolit lebih selektif meng¬adsorpsi Co2+ dibandingkan Ni2+. Natural Zeolite is selective adsorbent. To know the adsorption selectivity of natural zeolite fof Cott and Ni2+ is need adsorption constante. The methode that had been used by variation of beginning concentrations Co 2+, Ni2+, mixture CO2+ with Ni2+. The independent variable was the beginning concsntration and the constant variable kind and weight of zeolit, pH, temperatur, solven. From the experiment, it were formed that Adsorption constante of Co2+ was 1762,027 L mol "1, the maximum extensive surface covered by Co2+ was 2,21 x 10 mol L-1g-1. But adsorption constante of Ni2+ could not observed. The conclution from this experiment is Co2÷ more adsorpbed than Ni2+ in zeolite.
