Analisis Kandungan Oksida Logam Zeolit Alam Sulawesi Selatan Teraktivasi Asam Klorida

Abstract

Penelitian ini bertujuan untuk mengetahui kandungan oksida logam pada zeolit alam sebelum di aktivasi dan setelah diaktivasi. Aktivator yang digunakan adalah asam klorida 6 M. Analisis kandungan oksida logam dilakukan menggunakan instrument X-Ray Fluoresence (XRF). Hasil yang diperoleh menunjukkan, terjadinya penurunan kadar pengotor setelah zeolit teraktivasi asam. Kandungan Al2O3; SiO2; K2O dan CaO sebelum aktivasi berturut-turut adalah 2.15%; 86.34%; 4.32%; dan 2.54% adapun setelah aktivasi berturut-turut adalah 2.11%; 86.40%; 4.56%; dan 2.78%. Kandungan oksida logam lainnya (impuritis) pada umumnya mengalami penurunan kadar setelah zeolit teraktivasi.Kata kunci: oksida logam, zeolit, aktivasi asam This study aims to determine the metal oxide content of natural zeolite before being activated and after being activated. The activator used was hydrochloric acid6 M. Analysis of metal oxide content was carried out using the X-Ray Fluoresence (XRF) instrument. The results showed that there was a decrease in impurity levels after the zeolite was activated by acid. The content of Al2O3; SiO2; K2O and CaObefore activation were 2.15%; 86.34%; 4.32%; and 2.54% respectively, while after activation were 2.11%; 86.40%; 4.56%; and 2.78%respectively. The content of other metal oxides (impurity) generally decreases in levels after the zeolite is activated.Keywords: Metal oxide, zeolite, acid activated

Optimasi Kinerja Kombinasi Adsorben dalam Mereduksi Logam Besi dan Nikel Sampel Air

“…Beberapa penelitian terkait pemanfaatan zeolit alam lebih dikhususkan pada peningkatan efektivitas dan efisiensi proses industri dan pencemaran lingkungan (Putri dan Sabani, 2018;Setiawan dkk., 2018;Putri dan Side, 2020;Wijaya dkk., 2021). Pratomo dkk., (2017) melaporkan pemanfaatan zeolit alam teraktivasi asam fosfat (H 3 PO 4 ) sebagai adsorben ion Logam Cd (II) dalam laruta.…”

Utilization of Solid Waste PT Semen Bosowa as Zeolite for Industrial Waste Water in South Sulawesi

“…Adsorption occurs by the attractive force between the adsorbed molecule (adsorbate) and the adsorbing material (adsorbent). A molecule can be adsorbed if the adhesion force between the adsorbate molecule and the adsorbent molecule is greater than the cohesion force in each molecule [10].…”

“…The large surface is formed due to the presence of fine pores in the solid. In addition to surface area and pore diameter, distribution density and particle size are the most important characteristics of an adsorbent [10].…”

The Effect of Acid Treatment on Metal Oxide Content of South Sulawesi Natural Clay

“…Thus, based on the mineral constituent compounds, the Gowa district natural clay sample has a fairly high alumina silica content. In addition, Putri and Pratiwi (2017) also reported that natural clay from South Sulawesi has a high content of silica (65.39%) and alumina (9.02%) as well as some impurities contained therein such as Fe2O3 and TiO2. The high content of impurities in natural clay from South Sulawesi can affect the characteristics and durability of the material produced using clay as a raw material.…”

“…In Indonesia the utilization of clay is only for the manufacture of furniture and ceramics. The application of natural clay such as raw material for ceramic, adsorbent, and catalyst support (Putri et al 2018;Putri and Pratiwi 2016;Putri et al 2022). Even though the clay content in Indonesia which is spread across several provinces contains alumina silica which can be utilized in various sectors.…”
