Abstract


A B S T R A C T

Nickel hydroxide [Ni(OH)2] is an important compound in producing rechargeable batteries. The synthesis of Ni(OH)2 can be carried out using a hydroxide precipitation method from a solution containing nickel (II) (Ni2+) ions. In this study, the synthesis of Ni(OH)2 was investigated from the solution of extracted spent catalyst using sulfuric acid (H2SO4) solution. The selective precipitation was conducted using sodium hydroxide (NaOH) solution and the degree of acidity (pH) was varied in the range of 4–14. The operating temperature was kept constant at 30oC. The experimental results showed that the optimum precipitation conditions of Al3+ and Ni2+ ions were obtained at different pH where the optimum pH values were 6 and 10, respectively. Precipitate samples were characterized and the results showed that the purity of Ni(OH)2 in those samples was 13.1%. The XRD results indicated that the structure of precipitate still contains other impurities, such as Na2SO4, Al(OH)3 and those compounds were mutually agglomerate.

Nikel hidroksida [Ni(OH)2] merupakan senyawa penting dalam produksi baterai yang dapat didaur ulang. Sintesis senyawa Ni(OH)2 dapat dilakukan melalui metode presipitasi hidroksida dari suatu larutan yang mengandung ion nikel (II) (Ni2+). Pada studi ini, sintesis Ni(OH)2 dilakukan dari larutan induk hasil ekstraksi spent catalyst dengan menggunakan larutan asam sulfat (H2SO4). Proses presipitasi selektif dilakukan dengan menggunakan larutan natrium hidroksida (NaOH) dan derajat keasaman (pH) divariasikan pada kisaran 4 hingga 14. Temperatur operasi dijaga konstan pada 30 oC. Hasil percobaan menunjukkan bahwa proses presipitasi ion Al3+ dan ion Ni2+ mencapai keadaan optimum pada pH yang berbeda dengan nilai pH optimumnya adalah 6 dan 10, secara berurutan. Hasil karakterisasi sampel menunjukkan bahwa kemurnian Ni(OH)2 dalam sampel sebesar 13,1%. Hasil pengujian XRD mengindikasikan bahwa struktur presipitat yang terbentuk masih mengandung senyawa pengotor lain, seperti senyawa Na2SO4, Al(OH)3 dan senyawa–senyawa tersebut saling mengaglomerasi.
