Abstract

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.
