Use of flow injection analysis for the monitoring concentration of dissolved sulfides in post-processing water from underground coal gasification

摘要

Five samples of waste waters from gasification of bituminous coal and lignite were studied by flow injection anal. method to det. concn. of sulfide ions. Reliability of the results was evaluated by checking precision (variation coeff. lower than 6%) and accuracy (recovery 88-110%). The applicability of the anal. method used was confirmed.
