A Cloud point extraction (CPE) procedure was presented for preconcentration of lead(II) ions. after complexation by 18-crown-6 (18C6) and extraction with Triton X-100 at proposed experimental conditions. After separation of surfactant - rich phase. content of Pb(II) ions in remaining solution was measured by Flame Atomic Absorption Spectrometry (FAAS). https://leoners.shop/product-category/office-chair/
