Characteristics of Calcium Oxide from Pearl Shells (Pinctada Maxima) based on Calcination Te

“…The results in Figure 3 show that the highest content of CaO obtained on average is 21.31%. The content of CaO obtained in this study is different from previous studies because there are still organic compounds such as those that are still not completely decomposed during calcination [9].…”

“…Utilization of raw materials from shells is an alternative raw material that is environmentally friendly, inexpensive, and has a high content of calcium oxide compounds. Several researchers have investigated the content of CaO compounds, for example the study of the percentage of bases on clam shell powder which the results were quite high, namely 66,7% CaO, 22,28% MgO, 7,% SiO 2 , 1,25% AlO 2 and 0,03% Fe 2 O 3 [6], in the shell of Orbicularia orbiculara content CaO 98.5% [7], hell Anadara granosa 71% [8], Meretrix meretrix seashell 97%, shells Pinctada maxima 93.9% [9] Achatina fulica contain 98.629% CaO and Crassostrea gigas contain 57.06% [10] Research on the effect of variations in calcination temperature on porosity analysis CaO/ composites have also been carried out [11]. The results obtained that the porosity analysis at a temperature of 900°C has a pore volume of 0.007 cc/g and a surface area of 23,843 which means that the heating temperature affects the shape of the microstructure and the surface area on the sample surface.…”

Research on the utilization of raw materials from waste pearl shells (Pinctada maxima) has also been carried out using the ball mill CaO nanoparticles green, can be done by dry milling without the addition of solvents and a simpler purification process [9]. The research on the typical characteristics of CaO capable of being used as an adsorbent for heavy metal Pb was almost 100% carried out.…”

SODIUM LAURETH SULFATE (SLS) DECORATED α-PbO NANOCRYSTALS: OPTICAL, STRUCTURE, AND MORPHOLOGY, PROPERTIES

“…α-PbO nanocrystals has a 2 peaks with a particle size of 45 nm (peak 1) and 98 nm (peak 2). The particle size average distribution of α-PbO nanocrystals is 71.5 nm with a poly dispersity index (PDI) value of 0.3 as shown Figure 6(a) [18][19][20]. The results of PSA measurement showed α-PbO nanocrystals had a larger of particle size than the XRD results.…”

GREEN DEKORASI Au/ZnO NANOKOMPOSIT MELALUI MEDIA EKSTRAK DAUN GAHARU (Aquilaria malaccenensis L.) DAN PENENTUAN NILAI SUN PROTECTION FACTOR

“…Untuk mengurangi tingkat toksisitas sumber basa ini maka bisa digunakan sumber basa alami dari ekstrak tanaman. Ekstrak daun Aloe vera (Elizabeth and Mary 2015), Lemongrass (Anvekar, Chari, and Kadam 2017), Imperata cylindrica L Raeusch (Saputra et al 2020), Garcinia xanthochymus (Nethravathi et al 2015, Artocarpus gomezianus (Suresh et al 2015), Vitex negundo L (Ambika and Sundrarajan 2015), Carica papaya (Sharma 2016), Cylea barbata miers (Zuas, Kristiani, and Haryono 2015), Solanum nigrum (Ramesh, Anbuvannan, and Viruthagiri 2015), Agathosma betulina (Thema et al 2015), Moringa eleifera (Elumalai et al 2015), Tribulus terrestris (Zhao, Wang, and Liu 2015), Asphalathus linearis (Diallo et al 2015), Pongamia pinnata (Sundrarajan, Ambika, and Bharathi 2015), Plectranthus amboinicus (Fu and Fu 2015), dan Ficus carica Linn (Saputra et al 2021) berhasil difungsikan sebagai media dalam sintesis ZnO. Selama ini belum pernah dilakukan dekorasi Au terhadap permukaan ZnO dengan memanfaatkan ekstrak daun gaharu sebagai media.…”
