Tujuan penelitian ini adalah untuk menentukan pengaruh penambahan Na 2 CO 3 dan NaOH terhadap konsentrasi kadar Mg 2+ dan Ca 2+ pada garam krosok serta untuk mengetahui efektivitas penambahan flokulan polialuminium khlorida (PAC) dalam reaksi pengendapan CaCO 3 dan Mg(OH) 2 dengan metode rekristalisasi modifikasi spray. Metode yang dilakukan pada penelitian ini dengan cara menambahkan bahan pengikat pengotor yang harganya lebih murah seperti Na 2 CO 3 dan NaOH serta flokulan PAC yang dapat mengendapkan ion pengotor pada garam yaitu ion Ca 2+ dan Mg 2+ kemudian dilakukan rekristalisasi dengan modifikasi model spray untuk mendapatkan kristal NaCl yang lebih murni dengan lahan yang tidak begitu luas dan rekristalisasi meja kristalisasi penguapan . Hasil pemurnian garam krosok diperoleh kadar NaCl 98,53%, Ca 2+ 0,0600%, dan Mg 2+ 0,0288% dengan penambahan Na 2 CO 3 20% w, NaOH0,1 N dan PAC 10 ppm sebanyak 3 mL, yang telah sesuai standar industri Indonesia (SII).}, issn = {2597-9914}, pages = {50--54} doi = {10.14710/jksa.16.2.50-54}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/17924} }
