Abstract

Telah dilakukan penelitian pengaruh High Energy Milling (HEM) pada ukuran partikel dan kristalinitas zeolit alam untuk adsorpsi ion Cu(II) dan Ca(II). Penelitian ini bertujuan untuk menentukan pengaruh HEM pada ukuran partikel zeolit dan kristalinitas serta menentukan waktu  adsorpsi terbaik dengan zeolit alam dan zeolit alam milling. Metode penelitian dibagi menjadi tiga tahap, tahap pertama proses milling zeolit alam dengan HEM.  Tahap kedua karakterisasi zeolit dengan PSA dan XRD. Tahap ketiga adsorpsi ion  Cu(II) dan Ca(II) dengan kedua adsorben serta analisis perubahan konsentrasi dengan AAS. Hasil penelitian menunjukkan ukuran partikel zeolit alam dan zeolit alam milling berturut-turut adalah 3000 nm – 6000 nm, dan 288 nm – 540 nm. Hasil XRD menunjukkan kenaikan intensitas dan nilai 2θ dari zeolit milling terhadap zeolit alam. Perlakuan milling menyebabkan zeolit memiliki ukuran partikel lebih kecil sehingga zeolit alam milling mampu mengadsorpsi ion Cu(II) dan Ca(II) masing-masing 94,2% dan 35,69%. Perlakuan HEM mampu meningkatkan kemampuan adsorpsi Cu(II) dan Ca(II)
