Stibine and arsine generation from a lead--acid cell during charging modes under a utility load-leveling duty cycle. [2250-Ah cell at 5-h rate]
Technical Report

OSTI ID:7037552
An investigation was conducted to determine stibine and arsine generation during charging of a large industrial lead--acid cell (2250 Ah capacity at 5-h rate) under contemplated utility load-leveling duty cycles. The noxious gases generated were absorbed in a 3N H/sub 2/SO/sub 4/ solution containing KI and I/sub 2/. The antimony and arsenic contents of the absorber solutions were determined by colorimetry and atomic absorption spectrophotometry, respectively. Total emissions of stibine and arsine, as well as their generation-rate profiles, were determined each week in experiments consisting of four charge cycles and one equalization charge. In addition, hydride generation during successive, daily equalization charges was monitored. Generation of stibine and arsine from the lead--acid cell was found to be significant during the overcharge period of a charge cycle and during equalization charging at 2.65 and 2.55 V. 19 figures, 6 tables.
