Osmosis in Soils, II

Zn(II) Adsorption Study onto Soils of Sarcheshmeh Copper Mine

Soils around mining sites play a significant role in the transport and control of heavy metals in the environment. Therefore, understanding the adsorption properties of soil is essential in solving pollution problems. The objective of this paper was to study Zn(II) adsorption onto Sarcheshmeh copper mine soils. The adsorption isotherms of Zn(II) were studied. The Langmuir isotherm indicated an ...

Forward Osmosis as a Pre-treatment to Reverse Osmosis

This paper presents some aspects of forward osmosis coupled with reverse osmosis using a recirculating draw solution, to produce desalinated water or for dewatering/concentrating a feed stream, with some data provided from a number of operational sites. Many of these aspects are applicable to other osmotic processes and provide an insight into where they may be appropriately considered. A compa...

Osmosis in Cortical Collecting Tubules

This paper reports a theoretical analysis of osmotic transients and an experimental evaluation both of rapid time resolution of lumen to bath osmosis and of bidirectional steady-state osmosis in isolated rabbit cortical collecting tubules exposed to antidiuretic hormone (ADH). For the case of a membrane in series with unstirred layers, there may be considerable differences between initial and s...

Osmosis of Liquids

The present paper is a continuation of the series entitled "Equilibria in systems, in which the phases are separated by a semipermeable membrane," which have appeared in the proceedings of the Koninklijke Akademie van Wetenschappen (Amsterdam, Holland). In this paper I shall discuss in a simple form some of these results, viz. the osmosis of ternary liquids. The reader can find the thermodynami...
