“…The XRF method allowed for the analysis of the chemical composition or elements present in twenty-one samples in <3 h. The X-ray measuring time was only 200 s for the Al target and 100 s for other including RX9, Cu, and Mo secondary targets at room temperature at around 27°C. A detailed description of the XRF technique can be found elsewhere (Chaqmaqchee, Baker and Salih, 2017). Twenty-one salt samples have been collected from different locations in Kurdistan Regions-Iraq.…”

This study investigates the structure of 21 table salts that were collected from different local markets in the Kurdistan region of Iraq. The major trace elements and iodine concentrations in tablesalt are analyzed through the X-ray fluorescence (XRF) technique and the titration method, respectively. The study shows that using XRF spectral analysis, the collected table salt samples are rich in chlorine, sodium, and contain a lower percentage of bromine, strontium, tin, tellurium, and iodine. Moreover, these samples have a high percentage of sulfur and sirconium, where the molybdenum is >0.2%. Other elements such as zinc and copper are essential and found in low concentrations <0.0086% and 0.001%. Iodine is a trace element that is necessary nutrients for human life, and it is naturally present in some foods. Iodine deficiency is brought on by a lack of iodine consumption. Iodized salt is highly recommended as a source of iodine to prevent iodine deficiency disease. Iodine is added to table salt in two different ways, either through iodate or through iodine. The results show that only 25% of the salt samples have an adequate level of iodine, while the other samples have low or no iodine content. According to the World Health Organization, quality of salt depends on iodine concentration and other trace elements, which are necessary for human health.

“…The Frumkin adsorption isotherm is typically used with the Langmuir adsorption isotherm to compare the physisorption phenomena that occur on a heterogeneous surface region. The Temkin adsorption isotherm represents the chemisorption of an unmodified material on a heterogeneous substrate whereas the Freundlich [149,150].…”

Over the past decade, green chemistry has been emphasizing the importance of environmental sustainability and human health, aiming to minimize toxins and reducing wastes in an economically beneficial manner. The field of metallic materials deterioration, generally faced by the utilization of toxic compounds, discovered a promising research field in green chemistry. The application of inhibitors is a well-known strategy when metal corrosion needs to be avoided, prevented, controlled or mitigate. Green inhibitors are readily available, biodegradable, ecologically acceptable, sustainable and renewable sources. Their esteem broadens the numerous ranges of potential applications in various sectors besides “waste to energy” in the context of a circular economy. Extensive research on various biomass wastes such as corn stalks, nutshells, straw, forestry residue and plant waste-derived inhibitors tremendously has been utilized in corrosion mitigation in different industries to sustain the environment. All the mentioned aspects are the topic of this current review, which is meant as constructive criticism to spotlight the use of biomass waste as efficient green inhibitors in order to re-evaluate their viability and debate prospective research in the field, which is still lacking justification. As a result, this article aims to solve two current problems; waste and corrosion which will benefit both the environment and industry.

“…The sorting and processing will vary greatly from location to location due to different plastic waste collection processes, waste stream composition, recycling infrastructures, available equipment, and capacity, but also by the recycled plastic type market demand [21]. There are several separation and identification techniques which can be used, such as sinkfloat [65,66], froth flotation [67], near/mid infrared spectroscopy [68][69][70], X-ray fluorescence spectroscopy [71,72], hydrocyclones [73][74][75], tribo-electrostatic [76][77][78], magnetic density sorting [79,80], magnetic levitation [81,82], hyperspectral imaging [83][84][85], laser induced breakdown spectroscopy [86][87][88], hybrid jig [89], and many others. There are several reviews in the literature discussing the techniques, principles, advantages, and drawbacks in detail [18,46,79,[90][91][92][93][94].…”

Polyolefins and Polyethylene Terephthalate Package Wastes: Recycling and Use in Composites

et al. 2021

View full text Add to dashboard Cite

Plastics are versatile materials used in a variety of sectors that have seen a rapid increase in their global production. Millions of tonnes of plastic wastes are generated each year, which puts pressure on plastic waste management methods to prevent their accumulation within the environment. Recycling is an attractive disposal method and aids the initiative of a circular plastic economy, but recycling still has challenges to overcome. This review starts with an overview of the current European recycling strategies for solid plastic waste and the challenges faced. Emphasis lies on the recycling of polyolefins (POs) and polyethylene terephthalate (PET) which are found in plastic packaging, as packaging contributes a signification proportion to solid plastic wastes. Both sections, the recycling of POs and PET, discuss the sources of wastes, chemical and mechanical recycling, effects of recycling on the material properties, strategies to improve the performance of recycled POs and PET, and finally the applications of recycled POs and PET. The review concludes with a discussion of the future potential and opportunities of recycled POs and PET.
