“…It is worth mentioning that the constant amount of resin (1.6 g) was chosen according to the previous studies that used the UBK 10 resin for metal extraction purposes. [ 45,46 ] The effect of pH on lithium removal percentage is shown in Figure 1A. As can be seen from the figure, the optimal lithium removal percentage occurred at pH = 2.2, which is the original pH of the solution without being adjusted.…”

Selective recovery of lithium from Dead Sea end brines using UBK10 ion exchange resin

2022

The Dead Sea, a live pool of minerals and elements, holds ~9% of the world's known lithium reserves. However, the low lithium concentrations (30-40 mg/L) in the end brine and the high divalent to lithium ratio (Mg +2 + Ca +2 to Li + ) were obstacles that must be overcome to extract the lithium. In our previous work, lithium concentrations in the Dead Sea end brine were enriched by chemical precipitation up to 1700 mg/kg in the produced solid precipitate. The obtained precipitate was decomposed by doubledistilled water, and about 66% of lithium was leached, producing an environmental liquor containing an elevated concentration of lithium. A sequential ion exchange technique was used to achieve selective lithium recovery in this study. The ability of the UBK 10 strong acid-type cation exchange resin (Na type) to remove lithium from simulated and environmental lithiumbearing solutions was investigated. Because of the complex matrix comprising components that may compete with lithium adsorption, a greater quantity of adsorbent was required to achieve the equilibrium state for the environmental solution (7 g) compared to (3.6 g) for the simulated solution.For both lithium-bearing solutions, the kinetics investigation revealed a pseudo-second-order tendency. The interfering capacity was determined to be 0.405, confirming the UBK 10 challenge to selective lithium adsorption.The divalent to lithium ratio was decreased by more than 50 times, yielding encouraging findings for extracting lithium from the low lithium-high divalent to lithium sophisticated Dead Sea end brines.

“…Among the widely investigated alternatives for P recovery from wastewaters, adsorption by ion-exchange showed relatively low implementation costs than other treatment options. Concurrently, the costs of some of these materials depend on the source and synthesis conditions required to obtain them [125][126][127].…”

“…The process is based on the induction of PO 4 3− precipitation as amorphous calcium phosphate, hydroxyapatite, or struvite, using an electrical current. According to reports, these processes are fast, simple, eco-friendly, easily operable, and generate less sludge than the chemical routes [125,126,131,132].…”

Second-Generation Phosphorus: Recovery from Wastes towards the Sustainability of Production Chains

et al. 2021

View full text Add to dashboard Cite

Phosphorus (P) is essential for life and has a fundamental role in industry and the world food production system. The present work describes different technologies adopted for what is called the second-generation P recovery framework, that encompass the P obtained from residues and wastes. The second-generation P has a high potential to substitute the first-generation P comprising that originally mined from rock phosphates for agricultural production. Several physical, chemical, and biological processes are available for use in second-generation P recovery. They include both concentrating and recovery technologies: (1) chemical extraction using magnesium and calcium precipitating compounds yielding struvite, newberyite and calcium phosphates; (2) thermal treatments like combustion, hydrothermal carbonization, and pyrolysis; (3) nanofiltration and ion exchange methods; (4) electrochemical processes; and (5) biological processes such as composting, algae uptake, and phosphate accumulating microorganisms (PAOs). However, the best technology to use depends on the characteristic of the waste, the purpose of the process, the cost, and the availability of land. The exhaustion of deposits (economic problem) and the accumulation of P (environmental problem) are the main drivers to incentivize the P’s recovery from various wastes. Besides promoting the resource’s safety, the recovery of P introduces the residues as raw materials, closing the productive systems loop and reducing their environmental damage.

“…The existing phosphate recovery methods from urine mainly include chemical precipitation (Hu et al, 2020), ion exchange (Juntarasakul et al, 2020), membrane separation (Noubli et al, 2019) and adsorption methods (Zhang et al, 2020b). Among them, chemical precipitation method refers to adding magnesium salt to urine obtaining struvite precipitation (MgNH 4 PO 4 •6H 2 O) under alkaline conditions, which can be used as an alternative phosphate fertilizer (Kumari et al, 2020).…”
