Development of spectrophotometric determination of beryllium in beryl minerals using chrome Azurol S

Fluorine removal from high-fluorine beryllium ore by roasting and leaching pretreatment

“…Beryllium is a lightweight, naturally-occurring metal that is found in beryl, phenacite, chrysoberyl and bertrandite ores, its concentration is about 6 ppm in the earth's crust (Zaki et al, 2005;Fouad et al, 2011;Robert et al, 2010). Beryllium is a strategic metal due to its uses in electrical components, aerospace and nuclear energy, because of its low density combined with strength, low neutron absorption, high melting point, and high elastic modulus.…”

Surfactant assisted spectrophotometric determination of copper(II), and mercury(II) in real samples using 2- amino-4-((4- nitrophenyl)diazenyl)pyridine-3-ol

“…Copper is a vital element in plants [12] that can be used in alloy manufacture [13][14]. Chemically [15] or physically with foreign sources [16], it can be reached. Excess copper in the human body causes neuritis and cirrhosis by damaging the nervous system and organs, particularly the liver and gallbladder [17].…”

Selective extraction and determination of beryllium in real samples using amino-5,8-dihydroxy-1,4-naphthoquinone functionalized magnetic MIL-53 as a novel nanoadsorbent

“…Beryllium (Be) as one of the lightest (three times lighter than aluminium) and strongest metals (six times harder than steel) is a strategic metal because of its vital importance and applications in several industries. 1,2 Pure Be and its alloys with some metals, including Ni, Cu, Mg and Al, have been applied in aerospace components, electronic instrumentation, electrical equipment, the automotive industry, the nuclear industry, jewelry, ceramics, dental amalgams and prostheses. 1,3 Beryllium and its compounds can cause acute toxicity with the lungs as the target organ in human beings.…”
