Sustainable Production of Porous Activated Carbon from Hydrothermally Carbonized Jamoya Fruit Seeds and Its Potential for Adsorbing the Azo Dye Carmoisine B

Processes, Год журнала: 2025, Номер 13(2), С. 385 - 385

Porous carbon materials can serve as effective and versatile adsorbents in water pollution management. This study presents a cost-effective environmentally friendly method to produce porous (JFS-PC) by exploiting Jamoya fruit seeds (JFS) precursor using hydrothermal carbonization (HTC) process. HTC is thermochemical process for the conversion of high moisture content biomass into carbon-rich materials. The performed temperature range 180–250 °C during which submerged heated sealed environment under autogenous pressure. obtained were explored different techniques viz. XRD, FTIR, FE-SEM, surface area analyses evaluate their characteristics that are beneficial adsorption Surface analysis revealed developed activated exhibits appreciable (440.8 m2g−1), with mean pore diameter 3.97 nm. Activated was successfully tested on removal an azo dye, Carmoisine B (CB), from systems. Isothermal kinetic evaluation demonstrated dye agrees well Langmuir (R2 = 0.993) pseudo-second-order 0.998) kinetics models. experiments designed investigate influence adsorbate concentration (1 × 10−4 2 mol L−1), collision time (5–300 min), pH (2–12) solution, (25–45 °C) selected dye. results influences capacity CB showed maximum between 5. Experimentally, isotherms capacities 169.0 mg g−1, at 45 °C. Mechanisms indicate charge adsorbent, structures play key roles adsorption. Thermodynamic parameters endothermic physisorption supported Van’t Hoff calculations. indicates be used It also highlights use inexpensive renewable development

Aktivasyon Kimyasalı Türlerinin Metilen Mavisi Adsorpsiyonuna Etkilerinin İzoterm ve Kinetik Modelleri Kullanılarak İncelenmesi

Çukurova Üniversitesi Mühendislik Fakültesi Dergisi, Год журнала: 2025, Номер 40(1), С. 141 - 151

Опубликована: Март 26, 2025

Bu çalışmada, bazik, nötr ve asidik olmak üzere sırasıyla KOH, ZnCl2, H3PO4 aktivasyon kimyasalları ile işlemine tabi tutulan atık zeytin çekirdeklerinden 3 farklı aktif karbon eldesi gerçekleştirilmiştir. Mevcut çalışma eldesinde kullanılan kimyasallarının türü tipinin metilen mavisi adsorpsiyon mekanizmasına etkilerinin belirlenmesi amaçlanmıştır. Sentezlenen karbonlarla mavisinin çalışmaları gerçekleştirilerek giderim mekanizmalarına kimyasına etkileri incelenmiştir. Elde edilen kinetik izoterm verileri de giderimindeki mekanizmalar kirletici-adsorban ilişkileri belirlenmiştir. KOH aktivasyonunun yüzeyinde yüksek miktarda bölge oluşumu sağladığı, ZnCl2 aktivasyonlarında ise adsorpsiyona direnç gösteren bir tabaka varlığı olduğu tespit edilmiştir. Direnç tabakasının aktivasyonunda daha kalın adsorpsiyonuna gösterdiği Ayrıca, üç kimyasalıyla da elde karbonlar kimyasal tersinir gerçekleştirildiği sonucuna ulaşılmıştır.
