WebFor high-purity water used in semiconductor processing, the Semiconductor Equipment and Materials International (SEMI) recommends the use of IC for tracking trace ionic contaminants from 0.025 to 0.5 µg/L.2 To determine ions from mg/L (ppm) down to mid-µg/L (ppb) levels with IC, a sample size of 10 to 50 µL is sufficient. WebChitosan (abbreviated as ChT) solution was prepared by dissolving 0.1 g of ChT in 80 mL distilled water contains 1.0% glacial acetic acid then dissolve for 30 min using magnetic stirring. Once dissolved, 20 mL of 0.165% Sodium tripolyphosphate (TPP) solution was added drop wise to the ChT solution and the mixture was stirred for additional 15 min.
