“…68 Among the numerous nanoparticles, SiNPs are a unique class of inorganic nanoparticles with a wide range of functional properties, such as large surface area, high chemical stability, low toxicity, easy functionalization, easy synthesis, and good biocompatibility; key advantages such as modifiable surfaces and robust mechanical properties allow them to bind and functionalize with many compounds (functional species) or molecules, and they can be used for adsorption removal of FQs. 69 The combination of SiNPs and MIPs enables MIPs to have stronger selective adsorption ability and rapid response ability to template molecules. For decades, SiNPs have been used as biomaterials, which has good research significance.…”

The global rapid population growth is leading to accelerated food production thus accelerating the generation of agricultural wastes (AWs). Among the AWs management strategies is the valorisation of the AWs into useful products such as the production of silica nanoparticles (SNPs) which are useful in the road construction sector. Production of useful SNPs from AWs for the road construction industry is considered sustainable road construction, as not only does it reduces the carbon dioxide footprint from similar materials such as cement, but it is also cheap and readily available to low-income countries such as Kenya and Zambia. SNPs are of great importance in the production of high-strength materials such as stabilized soil and asphalt of significant strength than the conventional stabilised soil/asphalt with ordinary Portland cement. In this review, recent progress on AWs corresponding ashes (AWAs) with significant silica is studied. The production of SNPs from this AWAs is examined in detail concerning their synthesis methods for high purity SNPs, structure, phase, morphology, sizes, and their application in soil and asphalt stabilisation in road construction. The use of AWs to produce SNPs for use in the stabilisation of soils, bitumen, and asphalt for roads construction is promising, however, there is a need for further research on the large-scale production of SNPs from AWAs.

“…Exposure to MO and MB can cause severe illnesses and diseases such as skin irritation, dyspnoea, dermatitis, eye burn, and diarrhea [ 19 ]. Dyes are widely used in textile industries and are a major contributor to colored-wastewater production with high chemical oxygen demand (COD) concentration [ 20 , 21 ]. Printing and textile industries also produce anionic dyes including Orange G and Orange II that are considered to be teratogenic and carcinogenic in nature [ 22 , 23 ].…”

Kapok fiber (Ceiba pentandra) belongs to a group of natural fibers that are mainly composed of cellulose, lignin, pectin, and small traces of inorganic compounds. These fibers are lightweight with hollow tubular structure that is easy to process and abundant in nature. Currently, kapok fibers are used in industry as filling material for beddings, upholstery, soft toys, and nonwoven materials. However, kapok fiber has also a potential application in the adsorptive removal of heavy metal ions and dyes from aqueous systems. This study aims to provide a comprehensive review about the recent developments on kapok fiber composites including its chemical properties, wettability, and surface morphology. Effective and innovative kapok fiber composites are analyzed with the help of characterization tools such as scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and Brunauer-Emmett-Teller analysis. Different pre-treatment methods such as alkali and acid pre-treatment, oxidation pre-treatment, and Fenton reaction are discussed. These techniques are applied to enhance the hydrophilicity and to generate rougher fiber surfaces. Moreover, surface modification and synthesis of kapok fiber-based composites and its environmental applications are examined. There are various methods in the fabrication of kapok fiber composites that include chemical modification and polymerization. These procedures allow the kapok fiber composites to have higher adsorption capacities for selective heavy metal and dye removal.
