There is a special reason for reviewing this book at this time: it is the 50th edition of a compendium that is known and used frequently in most chemical and physical laboratories in many parts of the world. Surely, a publication that has been published for 56 years, withstanding the vagaries of science in this century, must have had something to offer. There is another reason: while the book is a standard fixture in most chemical and physical laboratories, including those in medical centers, it is not as frequently seen in the laboratories of physician's offices (those either in solo or group practice). I believe that the Handbook can be useful in those laboratories. One of the reasons, among others, is that the various basic items of information it offers may be helpful in new tests, either physical or chemical, which are continuously being published. The basic information may relate

Emulsion liquid membrane for heavy metal removal: An overview on emulsion stabilization and destabilization

The present paper on the supported liquid membrane (SLM) deals with the general principles and applications, followed by the uphill transportation characteristic of SLM. The liquid-liquid extraction with supported liquid membrane is one of the best alternate and promising technologies for the extraction of metal ions from solutions over other hydrometallurgical separation processes. The salient features of the supported liquid membrane (SLM) technique such as simultaneous extraction and stripping, low solvent inventory, process economy, high efficiency, less extractant consumption, and operating costs are discussed in detail. The supported liquid membrane of hollow fiber type provides high interfacial surface area for achieving maximum metal flux. Also the use of different organic extractants for SLM has been discussed.

Supported Liquid Membrane Principle and Its Practices: A Short Review

To obtain more stable W/O emulsion for liquid surfactant membrane technique, a series of glutamic acid dialkyl esters and dialkyl type quaternary ammonium salts as new surfactants in place of Span 80 and polyamine were synthesized. The adsorption equilibria between aqueous solution and organic solution containing the synthesized surfactants were elucidated and the stability of liquid surfactant membrane made of these surfactants was examined in a stirred tank. A series of synthesized surfactants having two long alkyl chains in hydrophobic site gave more stable emulsion at a lower concentration compared with Span 80 and polyamine. Among them, glutamic acid dioleyl ester formed the most stable emulsion.

Selective separation of cobalt and nickel by supported liquid membranes

This study reports the selective separation of Co (II) from mixtures of cobalt and nickel solutions using cellulose tri-acetate (CTA)-based polymer inclusion membranes, which incorporated the commercial extractant trioctylmethylammonium chloride (Aliquat 336) Tributylphosphate (TBP) was used as a modifier, and 2- nitro phenyl pentyl ether (2-NPPE) was applied as the plasticiser to prepare the membranes Several important transport parameters such as the plasticiser concentration, carrier type, carrier concentration, pH of acid, stirring speed, stripping solution type and concentration, complexing reagent (NH4SCN) concentration and synergistic effect of the modifier were discussed At the optimum conditions, following results were found: plasticiser concentration 02 mL, feed solution pH 4, feed phase stirring speed 900 rpm, stripping solution 1 M NH3 + 1 M TEA, complexing reagent (NH4SCN) concentration 05 M and modifier TBP 25% w/w Effective extraction was carried out under these conditions Th
