“…Moreover, the common pores from natural eggshells could not be found in the SEM image because the average pore size was 12.8 nm for AES900. 36 Moreover, the nal pH and stability of adsorbents also were discussed, and the results are listed in Table S1. † During the adsorption experiment, the initial pH was around 6.66, and the nal pH was around 10.51 for natural eggshells and eggshells with calcination temperature below 700 C. There is no obvious difference in the nal pH for eggshells with or without aging treatment, which are all around 12.01.…”

“…Penelitian limbah cair zat warna Batik Jambi akan didegradasi menggunakan sinar matahari dan sinar lampu UV dengan penambahan katalis CaO dari cangkang kerang bambu. Katalis CaO dipilih untuk proses fotokatalitik karena memenuhi kriteria yaitu zat ini tidak beracun, ramah lingkungan, rendah larut dalam air, dan biomaterial murah (Eskikaya et al, 2022).…”

“…Penelitian terdahulu mengatakan bahwa degradasi pewarna hijau dan merah fenol dengan penambahan CaO dari kulit telur ayam menunjukan hasil sebesar 98% dibandingkan tanpa adanya penambahan katalis hanya sebesar 78% (Thakur, 2021). Katalis serupa juga telah diujikan pada degradasi pewarna metilen biru dengan hasil 98% menggunakan sinar matahari dalam waktu 180 menit (Eskikaya et al, 2022). Sedangkan metode fotokatalitik untuk pewarna Safranin dan Reactive Red 180 (RR180) juga menggunakan katalis serupa menunjukan hasil degradasi pewarna Safranin dan RR180 masing-masing adalah 100% dan 97,90%, berurutan.…”

Limbah cair zat warna Batik Jambi mengandung senyawa organic non-biodegradable yang bersifat karsinogenik. Tujuan penelitian ini untuk mengetahui efektivitas katalis CaO dalam mendegradasi limbah cair zat warna Batik Jambi. Pada penelitian ini, limbah cair zat warna Batik Jambi didegradasi menggunakan metode fotokatalitik penyinaran matahari dan lampu UV 38 watt dengan dan tanpa katalis CaO dari cangkang kerang bambu. Larutan limbah warna dianalisis menggunakan spektrofotometer UV-VIS pada panjang gelombang 200-800 nm dengan massa katalis 0,02 gram. Data memperlihatkan bahwa hasil degradasi limbah cair zat warna Batik Jambi yang paling baik yaitu penambahan katalis CaO dan penyinaran matahari selama 3 jam sebesar 60,34%. Sedangkan penyinaran lampu UV selama 3 jam hanya sebesar 36,12%. Hasil penelitian dapat memberikan beberapa manfaat yaitu sebagai sumber informasi bagi pengrajin batik tentang pengolahan limbah cair Batik secara sederhana. Selain itu, studi ini sebagai data dukung bagi pemerintah tentang pembuatan produk hukum terkait pengolahan limbah cair batik yang belum terperhatikan. Kata kunci: Batik Jambi, CaO, degradasi, fotokatalitik, katalis ABSTRACT The wastewater of Batik Jambi dye contains non-biodegradable organic compounds that are carcinogenic. The purpose of this study was to determine the effectiveness of the CaO catalyst in degrading the Batik Jambi dye wastewater. In this research, Batik Jambi dye wastewater was degraded using the photocatalytic method the solar irradiation and a 38-watt UV lamp with and without a CaO catalyst from bamboo shells. The colored waste solution was analyzed using a UV-VIS spectrophotometer at a wavelength of 200-800 nm with a catalyst mass of 0.02 grams. The data showed that the best result of degradation of Jambi Batik dye wastewater was the addition of a CaO catalyst and solar irradiation for 3 hours of 60.34%. Whereas UV light irradiation for 3 hours was only 36.12%. The result of research could provide several benefits, namely as a source of information for batik craftsmen about the simple processing of liquid waste. In addition, this study served as supporting data for the government regarding the manufacture of law product related to the treatment of batik wastewater which has not been considered Keywords: catalyst, CaO, degradation, photocatalytic

“…It can even be used as a molecular adsorbent [6] [7] [8] while allowing it to adsorb heavy metals that cause environmental pollution due to the pores in its structure [9] [10]. There are studies in the literature about eggshells can be calcined and their ability to adsorb heavy metals or molecules can be increased [11] [12] [13] [14].…”

Aromatic nitro compounds, which have good water solubility, are one of the essential industrial pollutants, highly toxic and non-biodegradable, and adversely affect human health, aquatic life, and the environment. For this reason, eliminating these harmful organic compounds has become a subject of great importance and is frequently studied. In this study, we have investigated the adsorption of m-toluidine on three types of eggshells characterized by FT-IR and FT-Raman spectroscopy. Also, the theoretical analysis of these harmful organic was determined using density functional theory on GAUSSIAN 09 software program. Molecular electrostatic analysis, Infrared and Raman vibrational bands, frontier molecular orbitals, and molecular geometry were investigated for this purpose.
