โœฆ Synopsis

A simplified procedure for extracting ions from soil with ion-exchange resins is reported. The resin, placed in nylon-netting bags, were immersed in soil suspensions and shaken. Compared to the conventional procedure, where the resin beads are freely suspended in the soil-water mixture, this bagprocedure allowed quicker separation of resin from the soil suspensions. Furthermore, the severe soil grinding as done in the conventional procedure was eliminated. Phosphate was extracted from 4 Danish soils using both procedures. The bag-procedure resulted in slightly higher values than did the conventional procedure.

## Abstract A biphasic extraction system (CCl~4~/KH~2~ PO~4~) has been developed for the simultaneous removal of elemental sulphur (Sยฐ) and sulphate from soil. For five soils the recovery of Sยฐ (recovered as both oxidised S and residual Sยฐ) ranged from 96 to 100% at zero time of incubation. Due to
