摘要

本研究的目的是建立一个模型来确定Treptacantha barbata (Stackhouse) Orellana& Sansón, 2019(原Cystoseira barbata (Stackhouse) C. Agardh, 1820)的染料吸附效率。实验中采用初始染料亚甲基蓝(MB)浓度(0.1 ~ 10.0 mg L-1)、接触时间(5 ~ 1440 min)、吸附剂用量(0.1 ~ 2 g)等处理组。采用扫描电镜、能量色散x射线和傅里叶变换红外光谱对吸附剂进行了分析。在所有实验中,芭芭达对染料的去除率均达到69% ~ 100%,且qe值随初始染料浓度的增加而增加。在第一次接触时间内检测到非常快速的染料去除,特别是高达15分钟。等温线,动力学和回归模型应用于批量实验结果。结果表明,吸附过程符合Langmuir等温模型(R2: 0.97)。

Prediction models of dye adsorption by Treptacantha barbata
This study's objective was to develop a model to determine dye adsorption efficiency of Treptacantha barbata (Stackhouse) Orellana& Sansón, 2019 (formerly Cystoseira barbata (Stackhouse) C. Agardh, 1820). During the experiments, treatment groups, such as initial dye Methylene Blue (MB) concentration (0.1-10.0 mg L-1), contact time (5 to 1440 min) and adsorbent dosage (0.1-2 g) were applied. Scanning electron microscopy, energy dispersive X-ray, and Fourier Transform Infrared Spectroscopy were used to analyze the adsorbent. T. barbata was found to be quite successful in removing dye (69% -100%) for all experiments, and the qe values increased with the increased the initial dye concentration. Very rapid dye removal was detected during the first contact time, especially up to 15 min. Isotherms, kinetics, and regression models were applied to the batch experimental results. The results displayed that adsorption process was suitable with the Langmuir isotherm model (R2: 0.97).
