Parabens are a family of p-hydroxybenzoic acid esters used as preservatives in food, cosmetics, and pharmaceuticals products, parabens are pollutants that have been detected in the environment at low concentrations. Recent research describes that parabens can cause health alterations. Alternatives for contaminant removal include the adsorption process, which can use materials that are abundant, inexpensive and susceptible to modifications. In this sense, biochar can be an option for obtaining materials that can be used for pollutants removal. In this report, we present the use of biochar derived from fique bagasse as an adsorbent for the removal of butylparaben (BP) from water. This paper examines how pH variations influence the adsorption capacity of butylparaben onto fique bagasse biochar, it was determined that the highest adsorption capacity occurred at pH 6. Furthermore, pseudo-first order, pseudo-second order, Weber and Morris, and Boyd models were used to study the adsorption kinetics. As a result, the pseudo-first order model was favorable for six carbonaceous materials studied. Finally, Freundlich, Langmuir, and Sips adsorption isotherm models were investigated; the Langmuir model was the best for adsorption isotherm data. The maximum adsorption capacity of BP for FB-3Na was 20.9520 mg g.
对羟基苯甲酸酯是一类对羟基苯甲酸酯，用作食品、化妆品和药品中的防腐剂，对羟基苯甲酸酯是已在环境中检测到的低浓度污染物。最近的研究表明，对羟基苯甲酸酯会导致健康问题。去除污染物的替代方法包括吸附过程，该过程可以使用丰富、廉价且易于改性的材料。从这个意义上说，生物炭可以作为获得可用于去除污染物材料的一种选择。在本报告中，我们展示了使用从菲克甘蔗渣衍生的生物炭作为吸附剂从水中去除丁基对羟基苯甲酸酯（BP）。本文研究了pH值变化如何影响丁基对羟基苯甲酸酯在菲克甘蔗渣生物炭上的吸附容量，确定在pH值为6时吸附容量最高。此外，使用伪一级、伪二级、韦伯和莫里斯以及博伊德模型来研究吸附动力学。结果，伪一级模型对所研究的六种含碳材料是有利的。最后，研究了弗伦德利希、朗缪尔和西普斯吸附等温线模型；朗缪尔模型最适合吸附等温线数据。FB - 3Na对BP的最大吸附容量为20.9520 mg/g。
