An analytical procedure for straight-forward quantification of rare earth elements (REEs) in tea was developed. The method consists of three steps: first, dry tea powder is converted into an aqueous sample solution using a microwave-assisted digestion procedure. Then, the REEs are retained on newly designed sorbent particles and are thus effectively extracted from the sample digest. Then, the R...

Uranium, thorium, and rare earth elements (REEs) are important strategic in today’s world with a range of applications high green technology power generation. The expected increase demand for U, Th, REEs the coming decades also raises number questions about their supply risks potential environmental impacts. This review provides an overview current literature on distribution these different com...

The boom in technological advances recent decades has led to increased demand for rare earth elements (REEs) (also known as metals) across various industries with wide-ranging industrial applications, including the clean energy sector, but some environmental, economic, and social footprint concerns. This paper reviews complexities of production, consumption, reuse or recovery REEs, presenting c...

With their widespread application in industry, agriculture, medicine, and daily life, rare earth elements (REEs) are widely used in various fields and eventually accumulated in human body. Therefore, understanding the effects of REEs on health has become more and more important. In this work, the neurotoxicity of lanthanum (La) was evaluated. Wistar rats were exposed to lanthanum chloride throu...

Previously, proof-of-concept studies have demonstrated that rare-earth elements (REEs) can be preferentially extracted from coal fly ash (CFA) solids using a recyclable ionic liquid (IL), betainium bis(trifluoromethylsulfonyl)imide ([Hbet][Tf2N]). When the suspension of aqueous solution—IL-CFA—is heated above 65 °C, majority REEs will separate bulk in and partition to IL phase. Acid stripping r...

Arsenic and selenium presence in acid mine waters (AMWs) limits their disposal due to environmental regulations. The focus solve the economic infeasibility is directed sustainable solutions, promoting resource recovery. In fact, rare earth elements (REEs) recovery proposed most of Iberian Pyrite Belt AMWs. However, arsenic may impact REEs Among different alternatives, nanofiltration (NF) provid...

A number of studies have focused on the effects rare earth elements (REEs) crop plants, while little attention has been paid how tolerant plant species respond to increasing mixed REE concentrations. In this study, ramie (Boehmeria nivea L.) was exposed a series concentrations prepared with equimolar mixtures 16 REEs (i.e. 0, 1.6, 8, 16, 80, 160, 400, 800 μmol/L) in order explore accumulation a...

The initiative to electrify and decarbonize economies over the next two decades, particularly in energy transportation sectors, is going cause a significant increase demand for critical rare earth elements , Rare have already proved themselves highly useful, contributing many everyday items including batteries, electric vehicles, computer components, photovoltaic panels, turbines name few examp...

The European Union and several countries/regions classified the rare-earth elements (REEs), such as lanthanum, cerium, neodymium, scandium, critical due to risk of supply interruption. For this reason, growing demand for REEs has resulted in forgotten reserves receiving economic interest. So, search new sources development chemical process is important, silicate-based ore. Since there almost no...
