✦ Synopsis

H. V. MALMSTADT, J. I). WINEFORDNER null-point potcntiomctric m&hod. The complctc analysis time is about 3 min. Iodized salt samples containing 5-100 p.p.m. iodide were dctcrmincd with an average deviation IL& than 0.3 p.p.m. and with rclativc errors of about o.5(y0 at IOO p.p.m. and about 5% at 10p.p.m. iodide. The mcasured samples contained I--20 c(g of iodide in zo ml of solution, and thcsodium chloride to iodide weight ratio was as hi@ as 200.00r~ to I. Similar precision and accuracy were ohtaincd for prepared brines containing 10-200 p.p.m. iodide and a wide range of chloride to iodide ratios. %USAMMENFASSUNG Bcschrcibung ciner potcntiomctrischcn Bcstimmung von schr kleinen ivlcnr;cn Jod in Gcgcnwart von grossen Mengcn Chloritl.
