Due to the increasing environmental pollution caused by human activities, environmental remediation has become an important subject for humans and environmental safety. The quest for beneficial pathways to remove organic and inorganic contaminants has been the theme of considerable investigations in the past decade. The easy and quick separation made magnetic solid-phase extraction (MSPE) a popular method for the removal of different pollutants from the environment. Metal−organic frameworks (MOFs) are a class of porous materials best known for their ultrahigh porosity. Moreover, these materials can be easily modified with useful ligands and form various composites with varying characteristics, thus rendering them an ideal candidate as adsorbing agents for MSPE. Herein, research on MSPE, encompassing MOFs as sorbents and Fe 3 O 4 as a magnetic component, is surveyed for environmental applications. Initially, assorted pollutants and their threats to human and environmental safety are introduced with a brief introduction to MOFs and MSPE. Subsequently, the deployment of magnetic MOFs (MMOFs) as sorbents for the removal of various organic and inorganic pollutants from the environment is deliberated, encompassing the outlooks and perspectives of this field.

The water environment is mostly polluted by expanded industrial advancements and growth, which directly liberates various toxic pollutants into the water streams. These emerging pollutants cause several hazardous health issues to humans, animals, and the ecosystem. Conventional treatment methodology faces different issues in the recognition and removal of toxins, such as expense, facile operation conditions, and the prerequisite of high maintenance. To overcome this issue, adsorption is viewed as one of the most encouraging innovations for the removal of pollutants. Recently, metal-organic frameworks (MOFs) have been considered to be efficiently adsorbent, because of their porosity, high surface area, fine-tunable metal clusters, and easy functional surface engineering properties. This Review concerns the recent examinations on MOFs as proficient material in the removal of toxic contaminants from wastewater. The adsorption mechanism of toxic pollutants removal using MOFs-based materials was critically reviewed and discussed. At last, challenges and the viewpoint for future advancement of MOFs is summarized.

Lignocellulosic Biomass as Sorbent for Fluoride Removal in Drinking Water

Water supply to millions of people worldwide is of alarmingly poor quality. Supply sources are depleting, whereas demand is increasing. Health problems associated with water consumption exceeding 1.5 mg/L of fluoride are a severe concern for the World Health Organization (WHO). Therefore, it is urgent to research and develop new technologies and innovative materials to achieve partial fluoride reduction in water intended for human consumption. The new alternative technologies must be environmentally friendly and be able to remove fluoride at the lowest possible costs. So, the use of waste from lignocellulosic biomasses provides a promising alternative to commercially inorganic-based adsorbents—published studies present bioadsorbent materials competing with conventional inorganic-based adsorbents satisfactorily. However, it is still necessary to improve the modification methods to enhance the adsorption capacity and selectivity, as well as the reuse cycles of these bioadsorbents.
