Automated Nitrocellulose Analysis

Abstract

An automated method of analysis was developed for nitrocellulose in wastewaters, with specific provision for the removal of interfering nitrite ion. The procedure, utilizing a Technicon AutoAnalyzer, involves aspiration of a stirred nitrocellulose suspension, dialysis against 9 percent saline, and hydrolysis with 5N sodium hydroxide at 70 C for 10 minutes to release nitrite ion. Sulfanilic acid is diazotized by the nitrite ion at low pH. The resulting diazonium salt is coupled with N-(1-naphthyl)ethylenediamine, and the color so produced is measured at 520 nm. The limit of detectability of nitrocellulose is 0.4 mg/liter, well below the 1983 Best Available Technology Effluent Limitation for particulates, 10 mg/liter, which is likely to govern the discharge of nitrocellulose.
