Sub-structure of synthetic casein micelles
AM Knoop, E Knoop, A Wiechen - Journal of Dairy Research, 1979 - cambridge.org
Casein micelles of different composition were synthesized in various ways and their sub-
structure was investigated with the electron microscope by means of thin sections. Earlier
studies of Schmidt et al.(1974) using the freeze-fracturing technique had shown no …

The presence of cryptand 222 on the strongly acidic cation exchange resin Dowex 50WX8
(D) considerably increases its ability to remove strontium (Sr) from liquid milk. Dowex resin
treated with cryptand (D/222) sorbs more than 95% of the Sr in milk at pH 5.2 and 22° C after …

Use of liquid scintillation counting for fast determination of 89Sr and 90Sr in milk
D Tait, A Wiechen - Science of the total environment, 1993 - Elsevier
This paper describes a method of reproducibly recovering strontium (Sr) in 90.4% yield from
2-litre samples of raw milk in an analysis time of 5–8 h. All species which may interfere with
the measurement of 89 Sr and 90 Sr are effectively removed; decontamination factors for Ca …

Improvements to arapid method for separating strontium from liquid milk by treatment with a chelating resin and crown ethers
D Tait, A Wiechen - Journal of radioanalytical and nuclear chemistry, 1992 - Springer
In an attempt to improve on a previously reported method 1 for rapidly isolating Sr from liquid
milk, the following investigations have been carried out:(1) elution of strontium from a
chelating resin with dilute nitric acid,(2) separation of strontium from calcium by extracting …
