Optimization of cloud point extraction and solid phase extraction methods for speciation of arsenic in natural water using multivariate technique

The simple and rapid pre-concentration techniques viz. cloud point extraction (CPE) and solid phase extraction (SPE) were applied for the determination of As 3+ and total inorganic arsenic (iAs) in surface and ground water samples. The As 3+ was formed complex with ammonium pyrrolidinedithiocarbamat...
