Abstract

Acetylene gas waste possesses considerable potential for reutilization because of its high calcium content, although inadequate management may lead to adverse environmental effects. This research was conducted to synthesize and characterize multinutrient phosphate-based materials derived from acetylene gas waste through dissolution and precipitation techniques. The synthesis involved reacting calcium hydroxide obtained from acetylene gas waste with phosphoric acid (H?PO?), followed by a precipitation process using NH?OH and KOH solutions. The experimental variables included pH values ranging from 7 to 11 and H?PO? concentrations between 15% and 55%. Characterization of the synthesized products was performed using X-Ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), and X-Ray Diffraction (XRD) to evaluate elemental composition, crystal morphology, and crystalline structures. The findings revealed that higher pH values and increased H?PO? concentrations had a significant influence on both the yield and quality of the precipitated products. The maximum yield of 90% was achieved at an H?PO? concentration of 55% and pH 10. SEM observations revealed that the products exhibited a finer, more homogeneous crystal morphology, while XRF analysis confirmed that calcium was the dominant element, accompanied by phosphorus and potassium, indicating the successful synthesis of calcium phosphate-based materials. Furthermore, XRD analysis confirmed the formation of crystalline calcium phosphate compounds. Overall, the study highlights the potential application of acetylene gas waste as an alternative raw material for the production of sustainable and environmentally friendly phosphate fertilizers.

Abstract

Heavy metal contamination in aquatic environments is a serious environmental issue due to its toxicity, persistence, and tendency to accumulate within living organisms. One promising approach to address this problem is adsorption using aluminosilicate-based geopolymers. This study aimed to evaluate the ability of rice husk ash and metakaolin-based geopolymers to remove Pb²⁺ ions and to investigate the effects of Si/Al molar ratio and NaOH concentration on geopolymer characteristics, removal efficiency, and adsorption capacity. Geopolymers were synthesized using rice husk ash as a silica source and metakaolin as an alumina source with varying Si/Al molar ratios and NaOH concentrations. The synthesized geopolymers were characterized using SEM-EDX and FTIR, while their adsorption performance was evaluated based on Pb²⁺ removal efficiency and adsorption capacity from Pb(NO₃)₂ solution. The results demonstrated that the geopolymer was successfully synthesized and showed potential as an effective adsorbent for Pb²⁺ removal. SEM-EDX and FTIR analyses confirmed the formation of an aluminosilicate structure and indicated that Pb²⁺ adsorption involved ion-exchange mechanisms and interactions with active functional groups on the geopolymer surface. Variations in the Si/Al molar ratio and NaOH concentration significantly affected the characteristics and adsorption performance of the geopolymer. The optimum adsorption condition was achieved at a Si/Al molar ratio of 4.2 and a NaOH concentration of 10 M, resulting in an adsorption capacity of 7.94 mg/g and a removal efficiency of 99.83%.

Abstract

Limbah styrofoam merupakan sampah yang sulit terurai dan penggunaannya akan terus mencari lingkungan, sehingga diperlukan alternatif kemasan yang bersifat biodegradable. Penelitian ini bertujuan untuk mensistensis biodeogradable foam dari pati jagung dan limbah styrofoam dengan penguat serat bambu dan pengikat polivinil alkohol (PVA), dan gliserol sebagai plasticizer menggunakan metode baking. Variabel yang dikaji adalah massa pati (20,23,26,29, dan 32 gram) dan konsentrasi gliserol 20, 23,26,29, dan 32% dari massa pati). kemudian dilakukan karatkterisasi biofoam dilakukan melalui uji biodegradasi, uji daya serap  air dan uji kadar air. Hasil penelitian menunjukkan bahwa nilai biodegradasi tertinggi sebesar 28,67% pada komposisi pati 26 gram dengan gliserol 20%, sedangkan nilai terendah sebesar 5,6% pada pati 32 gram dengan gliserol 29%. Daya serap air tertinggi sebesar 19,5% pada pati 20 gram dngan gliserol 20% dan terendah sebesar 6% pada pati 32 gram dengan giserol 32%. Kadar air biofoam berkisar antara 9% hingga 14,4% yang masih memenuhi standar SNI sebesar 6-15%. Peningkatan glisserol dan massapati secara umum menurunkan biodegradasi dan daya serap air namun meningkatkan kadar air. Kombinasi pati 26 gram dengan gliserol 26% memberikan keseimbangan terbaik di antara ketiga karakterisasi tersebut, sehingga biofoam berbahan styrofoam dan pati jagung berpotensi sebagai alternatif kemasan ramah lingkungan.

Abstract

This study presents a sustainable approach for synthesizing calcium peroxide (CaO₂) nanoparticles from biogenic eggshell waste as a potential adsorbent for wastewater treatment. Increasing water pollution caused by industrial and domestic activities has driven the demand for low-cost and environmentally friendly adsorbents. In this study, eggshells from various poultry sources were calcined at 900°C to produce CaO, followed by hydration and chemical precipitation using H₂O₂ to synthesize CaO₂. The resulting materials were dried at different temperatures (60–100°C) to evaluate the effect of thermal treatment on structural properties and adsorption performance. X-ray diffraction (XRD) analysis confirmed the formation of CaO₂ with nanoscale crystallite sizes ranging from 15.3 to 28.85 nm. Brunauer–Emmett–Teller (BET) analysis showed specific surface areas between 10.18 and 19.67 m²/g. Adsorption experiments using acetic acid revealed that performance was significantly influenced by precursor type and drying temperature. The highest adsorption capacity (347.54 mg/g) and removal efficiency (34.75%) were achieved using CaO₂ derived from free-range chicken eggshells at 80°C. This enhanced performance is attributed to the natural biogenic structure, mineral composition, and pore distribution. Overall, eggshell waste is a promising, sustainable, and cost-effective precursor for producing high-performance CaO₂ nanoparticles for wastewater treatment
