Book Description
A solvent extraction process has been developed to purify nickel sulphate solution with respect to calcium and magnesium by extraction with a 20 per cent v/v solution of di-(2-ethylhexyl) phosphoric acid in Shellsol AB. The process uses six extraction stages to purify solutions containing 100 g/l nickel. The co-extracted nickel is stripped off the organic in four stages using sulphuric acid, and calcium and magnesium are stripped using hydrochloric acid in one stage. The stripped organic is pre-loaded with nickel in four stages before it is introduced into the extraction circuit. The purified raffinate is passed over an activated carbon bed to remove dissolved solvent before the crystallization of nickel sulphate. The development of this process, via batch tests and bench-scale counter current test work, is described. A plant capable of producing twelve tons of nickel sulphate heptahydrate crystals per day was designed and constructed, and the operation of this plant is described.

Book Description
The aim of this book is to provide an overview of the importance of stoichiometry in the biomedical field. It proposes a collection of selected research articles and reviews which provide up-to-date information related to stoichiometry at various levels. The first section deals with host-guest chemistry, focusing on selected calixarenes, cyclodextrins and crown ethers derivatives. In the second and third sections the book presents some issues concerning stoichiometry of metal complexes and lipids and polymers architecture. The fourth section aims to clarify the role of stoichiometry in the determination of protein interactions, while in the fifth section some selected experimental techniques applied to specific systems are introduced. The last section of the book is an attempt at showing some interesting connections between biomedicine and the environment, introducing the concept of biological stoichiometry. On this basis, the present volume would definitely be an ideal source of scientific information to researchers and scientists involved in biomedicine, biochemistry and other areas involving stoichiometry evaluation.

Book Description
Recent Advances in Liquid-liquid Extraction focuses on the applications of liquid extraction. The selection first discusses solvent extraction. Concerns include organic and inorganic separations, mass transfer process, solvent extraction economics, and coalescence in liquid-liquid systems. The book focuses on the chemistry of solvent extraction. Extraction by acidic organophosphorus compounds; extraction by phosphorus-bonded oxygen-donor solvents; extraction by high-molecular weight amines; and synergistic extraction are elaborated. The book also focuses on industrial organic processes; industrial contacting equipment; response characteristics and control of extraction processes; and calculation of contactors with longitudinal mixing. The selection presents the study of longitudinal mixing in liquid-liquid contactors. Rotating disc contactors, packed columns, vibrating plate extractors, and Oldshue-Rushton columns are described. The text also discusses heat transfer by direct liquid-liquid contact and the coalescence of liquid droplets and liquid dispersion. The selection is a vital source of data for readers interested in liquid extraction.
