“…REE are more abundant than many metals but their extraction involves several steps such as solvent extraction or ion exchange (Palmieri et al 2000). Although lanthanum has a wide range of applications in the industry, knowledge about its level of toxicity and possible recovery is limited.…”

In this study, the adsorption and desorption kinetics of lanthanum (La) on micro algal cells was investigated. The internal transcribed spacer (ITS) and 18S ribosomal RNA gene (rRNA) were used for molecular identification of the species. The algal species were found to have 95-98 % identities to Desmodesmus multivariabilis, Scenedesmus acuminutus, Chloroidium saccharophilum and Stichococcus bacillaris. The species were cultured and tested independently. Desmodesmus multivariabilis was found to be the most efficient at adsorbing lanthanum with a maximum sorption capacity (q max ) of 100 mg/g and a high affinity (b) of 4.55 L/g. Desorption of La was also highest in Desmodesmus multivariabilis with recovery up to 99.63% at initial concentration as high as 100 mg/L. Desorption data fitted best to the modified pseudo second-order with a better correlation coefficient (R 2 ) of ≤ 0.98 than first order model. The results showed feasibility of lanthanum recovery using algal sorbents, a cost effective method.

“…Microorganisms used for biosorption processes include bacteria, fungi, yeasts and algae. Differences in metal uptake are due to the properties of each microorganism such as cell wall structure, nature of functional groups and surface area (Palmieri et al, 2000). Beveridge (1989) showed that bacteria make excellent biosorbents because of their high surface-to-volume ratios and a high content of potentially active chemisorption sites such as teichoic acid present in the cell walls of Gram-positive bacteria.…”

“…Generally, the experiments take place at pH close to 5, below the pH of precipitation of REE hydroxide species. Some experiments have been carried out under acidic conditions (pH 1.5 and 0.6), thereby mimicking the acid nature of effluents (Palmieri 2000;Texier et al 1997;Karavaiko et al 1996;Andrès et al 1993). As described in Sect.…”

Microbial Biosorption of Metals

In Rare Earth Elements (REE) or Precious Metal Species (PMS) removal many types of biological phenomena can take place, such as biosorption, bioaccumulation, resistance/detoxification mechanisms, and direct or indirect utilization in the microbial metabolism. The high demand for the REE or PMS implies demand on increased production of ores containing REE or PMS (i.e. mining) and recycling of solutions to recover the elements contained in waste. But the use of REE and PMS in many anthropogenic applications and devices has led to an increased of public and environment exposure. The aim of this chapter is to compare under different operating conditions, the biosorption capacities of various microbial species and natural by-products for rare earth elements, to investigate the involved sorption mechanisms and to evaluate the potential industrial use of this process to metal ion removal.
