Abstract

An adsorber device for collecting diffusible ions in a liquid medium. The adsorber device includes an ion exchange "sink" comprising a hollow, spherical capsule filled with an ion exchange material or other adsorber. Further, the present invention includes a process for analyzing a test medium which includes scattering multiple adsorber devices throughout the test medium; recovering the devices after a predetermined amount of time; and leaching the accumulated solutes from the adsorber material to provide an extract solution which can then be analyzed by various procedures to determine quantities of accumulated solutes.

Claims

1. A free standing, self contained solute adsorber device comprising:

a pair of hollow, semi-spherical shells being joined together to form a hollow, spherical capsule;

the semi-spherical shells being formed of a porous, shape retaining material;

the adsorber device having an adsorber material held within the capsule.

2. An adsorber device according to claim 1 wherein the shells are constructed with a woven mesh fabric.

3. An adsorber device according to claim 1 wherein the adsorber material comprises a synthetic ion exchange resin.

4. An adsorber device according to claim 1 wherein the shells are constructed of a fibrous polyester fabric.

5. An adsorber device according to claim 1 wherein the adsorber material comprises a carbonaceous resin.

6. An adsorber device according to claim 1 wherein the adsorber material comprises a naturally occurring adsorber.

7. A process for recovering solutes from a medium comprising:

the scattering of multiple adsorber devices throughout the medium from which solutes are to be recovered, each adsorber device having a hollow spherical semi-rigid capsule made of porous material and having an interior and exterior surface with pores extending between the interior surface and the exterior surface and the capsule being filled with an adsorber material; and

recovering the adsorber devices.

8. A process for analyzing the quantity of solutes in a medium comprising:

the scattering of multiple adsorber devices throughout the medium from which solutes are to be recovered, each adsorber device having a hollow spherical semi-rigid capsule made of porous material and having an interior and exterior surface with pores extending between the interior surface and the exterior surface and the capsule being filled with an adsorber material;

recovering the adsorber devices; and

recovering the solutes from the adsorber material into an extract solution; and

performing an analysis of the solutes in the extract solution.

9. A process for analyzing the diffusion rate of solutes in a medium comprising:

the scattering of multiple adsorber devices throughout the medium from which solutes are to be recovered, each adsorber device having a hollow spherical semi-rigid capsule made of porous material and having an interior and exterior surface with pores extending between the interior surface and the exterior surface and the capsule being filled with an adsorber material;

recovering the adsorber devices after a predetermined period of time; and

recovering the solutes from the adsorber material into an extract solution; and

performing an analysis of the solutes in the extract solution.
