Data Repository for Adsorption Kinetics of Perfluorononanoic Acid (PFNA) and Perfluorodecanoic Acid (PFDA) on Biochar

This data repository contains the experimental data from a study investigating the adsorptive removal of perfluorononanoic acid (PFNA) and perfluorodecanoic acid (PFDA) using biochar as the adsorbent. The dataset provides detailed measurements of PFNA and PFDA concentrations over time, as well as the corresponding biochar characteristics, including particle size and weight. The study aimed to evaluate the effectiveness of biochar, derived from different sources, in adsorbing long-chain perfluoroalkyl carboxylic acids (PFCAs) from aqueous solutions. The dataset includes time-resolved concentration data of PFNA and PFDA, which are critical for understanding the kinetics of adsorption. The experiments were conducted with specific biochar sizes ranging from 841 to 1000 microns and at a consistent biochar weight of 25 mg. Researchers and practitioners can use this dataset to model adsorption kinetics, evaluate the performance of biochar as an adsorbent, and develop predictive models for PFCA removal in water treatment processes. The dataset is suitable for use in various analytical and computational studies, including those focused on environmental engineering, water treatment, and adsorption process optimization.本数据集仓库收录了一项以生物炭（biochar）为吸附剂，探究全氟壬酸（perfluorononanoic acid, PFNA）与全氟癸酸（perfluorodecanoic acid, PFDA）吸附去除效果的实验数据。该数据集包含PFNA与PFDA随时间变化的浓度详细测量值，以及对应生物炭的各项特性参数，包括粒径与质量。 本研究旨在评估不同来源生物炭对水溶液中长链全氟烷基羧酸（perfluoroalkyl carboxylic acids, PFCAs）的吸附效果。数据集涵盖PFNA与PFDA的时间分辨浓度数据，这对解析吸附动力学至关重要。本次实验所用生物炭的粒径范围为841至1000微米，且固定生物炭投加质量为25毫克。 研究人员与工程实践者可利用该数据集开展吸附动力学建模、评估生物炭作为吸附剂的性能，并开发水处理过程中PFCAs去除的预测模型。该数据集适用于各类分析与计算类研究，涵盖环境工程、水处理及吸附工艺优化等研究方向。
