利用活性炭去除Isoniazid的研究
Removal of Isoniazid from Aqueous Solution through Activated Carbon from Different Raw Materials
摘要
一些研究表明製藥業會產生包含地表水和地下水中的污染物。異煙肼為水體中毒性最大的製藥污染物之一，需要進一步研究，以減少其對環境的影響，其中一種方法是通過吸附。活性炭由阿勃勒樹豆莢和豆漿渣合成，農業廢物可用作活性炭生產的潛在低成本前驅物。本文介紹了豆漿殘留物和阿勃勒樹豆莢作為活性碳的前驅物的最新進展。在這項研究中，測試了三種活性炭（豆漿渣活性碳，阿勃勒樹豆莢活性碳和市售活性碳）。依序採用水熱法和熱解法製備出活性炭。用K2CO3浸漬的原料直接熱解。使用批量實驗方法進行等溫吸附研究，然後使用Langmuir，Freundlich和Dubinin-Raduskevich等溫模型進行建模。使用不同前驅物的活性碳吸附異煙肼，並且市售活性碳作為比較，均遵循Freundlich等溫模型。在活性碳上的可能機制是由偶極 - 偶極和氫鍵的相互作用，π-π相互作用和n-π相互作用產生的。由DR模型（Qdr）測定的最大吸附容量表現出以下順序阿勃勒樹豆莢活性碳（1.25）（249.86mg / g）> 豆漿渣活性碳（1.75）（151.35mg / g）>市售活性碳（133.88mg / g）。

Several studies have demonstrated the presence of pollutants from the pharmaceutical industry in surface and groundwater. Isoniazid as one of the most toxic pharmaceutical pollutant in water body needs further study to reduce its environmental impacts, one of the methods is by adsorption. Activated carbon was synthesized from golden shower and soybean milk residue, agricultural wastes can be employed as potential low-cost precursors for AC production. This paper presents a recent advancement in the utilization of soybean milk residues and golden shower as the precursor of the AC production. In this study, three kinds of ACs were tested (SAC, GAC and CAC). Hydrothermal and pyrolysis process was employed to get activated carbon in sequence. Raw materials were impregnated with K2CO3 were directly pyrolyzed. Isotherm adsorption studies were performed using batch experimental approach and then modeled with Langmuir, Freundlich, and Dubinin-Raduskevich isotherm models. Adsorption of isoniazid using different produced ACs, and commercial AC as a comparison, are all following the Freundlich isotherm model. A possible mechanism that occurs on AC are dipole-dipole and Yoshida H bonding interactions, π-π interaction and n-π interaction. The maximum adsorption capacities determined from DR model (QDR) exhibited the following order GAC(1.25) (249.86 mg/g)>SAC(1.75) (151.35 mg/g)>CAC (133.88 mg/g).
