“…As for other valuable metals, attempts have been made by Marczenko and Kalinowski [118] for the recovery of Pt(SnCl 3 ) 5 3-with basic dyes, and by Berg et al [119] for the separation of IrCl 6 2-and RhCl 6 3-from hydrochloric acid solutions using hexadecyltripropylammonium (HTPAB) through ion flotation followed by solvent sublation. In both cases, separation was possible but the performance was poor.…”

Foam separation has been applied to recover or remove various substances from dilute aqueous solutions in various industries because it is an environment-and cost-friendly process. The literature has been reviewed focusing on the separation of metal ions.From an operational point of view, various methods are discussed for the removal of metal ions from solution, and on the selective recovery of a specific target metal ion.The former applications are designed to purify industrial effluents, and the performance of foam separation is well proven. The latter examples are aimed at recovering valuable metals, which has been shown to be difficult due to the inherent problem of contamination in foam separation. An operation mode was developed to overcome this problem and to enhance the selectivity for separating a specific target metal from solutions containing multi-metals. The method, called continuous counter-current foam separation, was developed, and its performance was demonstrated by the experimental results for Ga(III) separation. Since both high selectivity and recovery was obtained by this method, foam separation is potentially a "solvent-free" alternative to solvent extraction.

Reviews[Part 4, fractional replication, confounding, response surface, change-over trials and incomplete block designs. The book is written in a succinct style sometimes reminiscent of lecture notes. Considerable space is devoted to worked examples though no problems are presented for students to work on themselves.Little new material has been added to Anderson and McLean's Design of Experiments: A Realistic Approach. (Marcel Dekker, 1971) which this text supersedes though the order of presentation is different. Most of what is covered appears in greater detail in Cochran and Cox's Experimental Designs. (2nd ed., Wiley, 1957). The author adopts a prescriptive style of teaching which stresses what to do rather than why to do it. A distinctive feature about this book is the inclusion of the "Report of Statistical Analysis" sections. These tell the researcher exactly how to write up the analysis of each design. This emphasis on standardisation makes the analyses easier to follow at the expense of distancing a reader from the phenomena under investigation. The analyses are specified quite independently of how the results turn out. An inflexible approach is also encouraged by not providing possible options. A related problem is that little emphasis is placed on theory, numerical examples being used to clarify inadequate explanations of topics.Particular omissions which might be seen as important include:-An adequate coverage of the random factor models and how they affect significance testing in other than one factor designs, the analysis of contingency tables, the treatment of outliers, the possible use of transformations and the analysis of residuals. In the chapter on change-over trials examples are given where order effects are not examined. This could have unfortunate consequences if the text were being used as a cook book.To sum up this is a text covering traditional topics in experimental design. It should enable the statistically naive to analyse complex experiments but it is not designed to make them understand what they are doing.
