Recent advances in lignin-based carbon materials and their

Lignin is composed of p-hydroxyphenyl (H), guaiacyl (G), and syringyl (S) through various chemical bonds (Fig. 1).It contains a large number of benzene rings with high carbon content up to 60 %, making lignin an ideal precursor for carbon materials [2].Therefore, it is highly desirable to convert lignin into functional carbon materials Furthermore, they have also shown substantial performance and important characteristics for remediation for removing pollutants from water, watercourse, and effluents. After its uses, gelatin-based hydrogels can easily biodegrade and, thus, can be sustainably used in the environment. In this study, gelatin was shown to be a potential Gelatin-Based Hydrogels: Potential Biomaterials for Remediation

Review of Treatment Technologies for the Removal of Phenol from

Abstract Phenol is an important chemical used in many industries as a raw material, such as, pharmaceutical and rubber, oil and petroleum refineries, pulp and paper manufacturing plants, iron and steel, etc. Phenol and its derivatives are one of the largest groups of environmental pollutants owing to their presence in many industrial effluents The remediation of mercury (Hg) contaminated soil and water requires the continuous development of efficient pollutant removal technologies. To solve this problem, a biochar–bentonite composite (CB) was prepared from local millet straw and bentonite using the solution intercalation-composite heating method, and its physical and chemical Preparation of a Novel Millet Straw Biochar-Bentonite Composite

If the sodium content is more dominant, the bentonite is Na-bentonite, and vice versa. From the results of EDX bentonite milling analysis, it is known that the ty pe of bentonite is Na-Bentonite. The most chemical elements are Si, Al, and O which are characteristic of t he composition of bentonite compounds such as the [13] while F is the impurity.Novel hybrid carbon–mineral materials were synthesized by the mechanochemical activation of a mixture of tannin and bentonite in a ball mill with further pyrolysis in an argon atmosphere at 800 °C. The influence of the initial mixture ingredients content on the structural, textural, and thermal characteristics of biochars has been Development, Synthesis and Characterization of Tannin/Bentonite

Sustainable bioplastics derived from renewable natural resources

Bioplastic is produced from natural renewable resources such as crops, wood pulp, and herbaceous fibers. This article summarizes the rational design of bioplastics from natural resources for food packaging. The bioplastic properties considered include thermal properties, mechanical performance, oxygen/moisture resistance, and Pulp and paper industry is one of the largest water polluters in the world. The high water usage results in large amounts of wastewater generation [1].It has been estimated that the pulp and paper industry is responsible for 50% of all wastes dumped into Canada’s waters [2].Recent years, for example in China, the discharge of national Application of modified bentonite granulated electrodes for advanced
