Penelitian ini juga mengkaji pengaruh keberadaan ion Cu2+ di dalam sistem pertukaran kation. Konsentrasi ion-ion dianalisis dengan metode spektrofotometri serapan atom. Data eksperimen menunjukkan bahwa zeolit alam yang telah dimodifikasi dengan Na+ dapat digunakan untuk mengambil ion Mn2+ dan Ni2+ melalui mekanisme pertukaran kation. Uji selektivitas memperlihatkan bahwa Na-Zeolit lebih selektif terhadap Mn2+ dibandingkan terhadap Ni2+. Urutan selektivitas ini tidak dipengaruhi oleh keberadaan Cu2+. Na-Zeolit mampu mempertukarkan kation Mn2+ sampai 57,73 % dalam keadaan sendiri dan 19,72 % dalam keadaan bersama; Ni2+ sampai 37,71 % dalam keadaan sendiri dan hanya 5,81 % dalam keadaan bersama kation logam lain di dalam larutannya.}, issn = {2597-9914}, pages = {35--38} doi = {10.14710/jksa.7.2.35-38}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/3328} }
