摘要

原油开采经常与泄漏有关，导致环境污染。研究了海藻酸钠壳聚糖水凝胶聚电解质复合吸附剂在原油污染水处理中的应用。将壳聚糖与海藻酸钠按1:9 ~ 9:1的比例混合，考察了pH值和污染浓度与水凝胶-聚电解质吸附剂比例的关系。采用间歇吸附等温线法评价了制备的效率。对水凝胶进行了x射线衍射和扫描电镜分析，评价了表面积对吸附的影响。结果表明，pH、吸附剂比和原油浓度对吸附效果有显著影响。具体来说，随着pH值的增加，吸附量下降。壳聚糖与海藻酸钠的比例越高，对原油的吸附也越少。综上所述，本研究揭示了SACHPC吸附剂在原油污染修复中的吸附潜力。

Preparation and application of sodium alginate-chitosan hydrogel polyelectrolyte complex adsorbent for treatment of oil spillage

Crude oil extraction is often associated with spillage leading to environmental pollution. The present study investigates the application of sodium alginate chitosan hydrogel polyelectrolyte complex adsorbent in the treatment of crude oil-polluted water. Chitosan was mixed with sodium alginate in nine ratios (1:9 to 9:1), and examined based on pH and concentration of pollution, in relation to the proportion of hydrogel-polyelectrolyte adsorbent. The efficiency of the preparation was evaluated using batch adsorption isotherm. X-ray diffraction and scanning electron microscopy of the hydrogel were carried out to evaluate the impact of surface area on adsorption. The results obtained revealed that adsorption was significantly affected by pH, adsorbent ratio and crude oil concentration. Specifically, there was a decline in adsorption as pH increased. Higher ratio of chitosan to sodium alginate also resulted in less crude oil adsorption. Overall, the study revealed the adsorption potential of SACHPC adsorbent in remediating crude oil pollution.

期刊介绍： Chemical Data Collections (CDC) provides a publication outlet for the increasing need to make research material and data easy to share and re-use. Publication of research data with CDC will allow scientists to: -Make their data easy to find and access -Benefit from the fast publication process -Contribute to proper data citation and attribution -Publish their intermediate and null/negative results -Receive recognition for the work that does not fit traditional article format. The research data will be published as ''data articles'' that support fast and easy submission and quick peer-review processes. Data articles introduced by CDC are short self-contained publications about research materials and data. They must provide the scientific context of the described work and contain the following elements: a title, list of authors (plus affiliations), abstract, keywords, graphical abstract, metadata table, main text and at least three references. The journal welcomes submissions focusing on (but not limited to) the following categories of research output: spectral data, syntheses, crystallographic data, computational simulations, molecular dynamics and models, physicochemical data, etc.
