Funding information TUBITAK, Grant/Award Number: CAYDAG-113Y533 Abstract Polymer-derived ceramic components (SiOC, sample W) were produced from preceramic polymer mixture and a catalyst. After curing and pyrolysis, some of the samples etched by hydrofluoric acid to obtain carbonaceous SiOC (C-rich SiOC, sample W-HF). W and W-HF were tested as an adsorbent material to remove both heavy-metal ions (Cr (III), Pb (III), and Cd (II)) and cationic dyes (Methylene Blue (MB), Rhodamine B (RB), and Crystal Violet (CV)) from aqueous solutions. HF-treated high surface area SiOC samples had quite high adsorption affinity for cationic dyes. According the Langmuir isotherm model the maximum dye uptake values were found to be around to 50 mg/g for sample W, whereas those for sample W-HF ranged from 104 to 186 mg/g. Regeneration studies were conducted both by heat treatment and leaching, high recovery yields (always above 97%) of MB adsorption were obtained.

资金信息 TUBITAK，资助/奖励编号：CAYDAG-113Y533 摘要 聚合物衍生的陶瓷组件（SiOC，样品 W）由陶瓷前体聚合物混合物和催化剂制成。固化和热解后，部分样品用氢氟酸蚀刻得到碳质SiOC（富CSiOC，样品W-HF）。测试 W 和 W-HF 作为吸附材料，可去除重金属离子（Cr (III)、Pb (III) 和 Cd (II)）和阳离子染料（亚甲蓝 (MB)、罗丹明 B (RB)）和结晶紫 (CV)) 来自水溶液。HF 处理的高表面积SiOC 样品对阳离子染料具有相当高的吸附亲和力。根据朗缪尔等温线模型，发现样品 W 的最大染料吸收值约为 50 mg/g，而样品 W-HF 的最大染料吸收值为 104 至 186 mg/g。
