Taurite (shungite), natural zeolite, and coconut-shell activated carbon 207C were tested in single- and multicolumn configurations at 100 and 150 cm3 per sorbent layer. Pb and Cd reduction were evaluated in fortified milk, while pre-existing 137Cs and 90Sr were assessed in milk from two locations. Milk-quality parameters were measured in separate milk batches. At 150 cm3 per layer, taurite\u2192activated carbon reduced Pb and Cd by approximately 90.6% and 91.9%, respectively, to 0.032 and 0.025 mg\/kg. Under the 150 cm3 radionuclide-testing conditions, zeolite\u2192activated carbon reduced 137Cs and 90Sr by 75.73% and 73.97%, yielding residual activities of 0.2534 and 0.1123 Bq\/kg. The complete three-stage configurations achieved approximately 79.9% and 77.7% reductions, respectively. In the separate quality assessment, taurite\u2192activated carbon produced limited changes in basic composition and viscosity, whereas zeolite-containing configurations caused greater decreases in Na and K. Radionuclide results were interpreted within each source-specific series because milk source and sorbent loading varied simultaneously. Overall, the findings demonstrate substantial laboratory-scale contaminant reduction and support selecting sorbent configurations according to contaminant type, with taurite\u2192activated carbon providing a favourable balance across the separately assessed removal and milk-quality criteria.<\/jats:p>","DOI":"10.3390\/foods15193413","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T10:16:28Z","timestamp":1790244988000},"page":"3413","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Multistage Adsorption\u2013Filtration of Cow\u2019s Milk for Heavy Metal and Radionuclide Removal with Preservation of Milk Quality"],"prefix":"10.3390","volume":"15","author":[{"given":"Aray","family":"Bazanova","sequence":"first","affiliation":[{"name":"Research School of Food Engineering, Shakarim University, 20A Glinki Street, Semey 071412, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"}]},{"given":"Aitbek","family":"Kakimov","sequence":"additional","affiliation":[{"name":"Research School of Food Engineering, Shakarim University, 20A Glinki Street, Semey 071412, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"}]},{"given":"Marzhan","family":"Tashybayeva","sequence":"additional","affiliation":[{"name":"Research School of Food Engineering, Shakarim University, 20A Glinki Street, Semey 071412, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"data-curation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0830-5007","authenticated-orcid":false,"given":"Alibek","family":"Muratbayev","sequence":"additional","affiliation":[{"name":"Research School of Food Engineering, Shakarim University, 20A Glinki Street, Semey 071412, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"software","vocabulary":"credit"}]},{"given":"Nazerke","family":"Muratzhankyzy","sequence":"additional","affiliation":[{"name":"Research School of Food Engineering, Shakarim University, 20A Glinki Street, Semey 071412, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"resources","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"}]},{"given":"Nadir","family":"Ibragimov","sequence":"additional","affiliation":[{"name":"Research School of Food Engineering, Shakarim University, 20A Glinki Street, Semey 071412, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"conceptualization","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Antunes, I.C., Bexiga, R., Pinto, C., Roseiro, L.C., and Quaresma, M.A.G.
