Chitosan is a biocompatible polymer with vast applications in pharmacology, medicine, paper making, agriculture, and the food industry due to its low toxicity. Chitosan also plays an important role in the sustainable environment since chitosan is able to absorb greenhouse gases, harmful organic matter, and heavy ions. Therefore, this paper conducts a bibliometric analysis of chitosan for sustainable development using the Scopus database from 1976 to 2023. A performance analysis on the 8002 documents was performed with Harzing’s Publish or Perish. Science mapping was conducted using VOSviewer. The annual publication on chitosan for sustainable development showed an upward trend in recent years as the annual publication peaked in 2022 with 1178 documents with most of the documents being articles and published in journals. Material science, chemistry, and engineering are tightly related subject areas. China had the highest publication of 1560 total documents while the United States had the most impactful publication with 55,019 total citations, 68.77 citations per document, 77.6 citations per cited document, h-index 110, and g-index of 211. India had the largest international collaboration with 572 total link strength. “International Journal of Biological Macromolecules”, “Carbohydrate Polymers”, and “Polymers” have been identified as the top three source titles that publish the most documents on chitosan for sustainable development. The emerging trends in chitosan on sustainable development focus on the application of chitosan as an antibacterial agent and biosorbent for contaminants, especially in water treatment.

“…13 The discharge of wastewater that has not been fully or adequately treated is the main source of pharmaceuticals in the environment. 14 It is important that unwanted medicines should be safely disposed of to mitigate public and environmental health risks. Lack of general knowledge on how to dispose of unused pharmaceuticals leads to improper disposal, resulting in accidental toxicity, rising healthcare costs, landfills pilfering/scavenging, water supply pollution, antimicrobial resistance, and death.…”

The majority of pharmaceuticals are found in the environment as mixtures. However, a significant amount of these therapeutic compounds cannot be completely metabolized by the human body; thus, they are excreted through feces and urine and end up in wastewater treatment plants (WWTPs). The presence of pharmaceuticals and the degree to which they can be removed during wastewater treatment are now important research topics. Despite the adoption of various alternative technologies for the treatment of wastewater, the adsorption process is still regarded as a promising method due to its high efficiency, increased simplicity, and lower costs. Recent developments in the adsorption process involve the incorporation of an artificial molecularly imprinted polymer (MIP), which is a potent molecular receptor capable of selectively recognizing and removing pollutants. The MIP has advantageous characteristics, which include high affinity, predetermination, high stability, ease of preparation, and low cost. Notably, MIPs can be applied to the cleanup and preconcentration of analytes as the selective adsorbent of solid-phase extraction (SPE), magnetic solid phase extraction (MSPE), and dispersive solid-phase extraction (dSPE). Furthermore, MIPs can be produced as composite nanomaterials by employing nanoparticles (nanoMIP). The advancements of MIPs employed as sorbent materials for quantitative assessment and purification of pharmaceuticals in environmental water have been given most of the focus. Therefore, this study not only aims to present the fundamental ideas about the application of MIPs as sorbents but also gives an overview of the considerable initiatives made in recent years to enhance the performance of MIPs. Considering this, various current approaches to the development of MIP-based extraction techniques are detailed in the present review. This review also demonstrates how kinetics, thermodynamics, and isotherm models can be used to better understand the behavior of adsorbents and the adsorption process.
