Removal of natural organic matter for wetland saline water desalination by coagulation-pervaporation
Jurnal Kimia Sains dan Aplikasi, 2019 The high number of natural organic matter contain in wetland water may cause its water has brown color and not consumable. In other hand, intrusion of sea water through wetland aquifer create water become saline, notably on hot season.

Sequential Spectrophotometric determination of methanol and iron in vinegar by a flow injection-pervaporation method [PDF]
, 2002 An easily automatable sequential flow-injection-pervaporation method is proposed for the photometric determination of methanol and iron in vinegar. The method is based on separation of the methanol from the sample matrix by pervaporation followed by its ...

Integrally skinned polysulfone hollow fiber membranes for pervaporation [PDF]
, 1994 From polysulfone as polymer, integrally skinned hollow fiber membranes with a defect-free top layer have been spun. The spinning process described here differs from the traditional dry-wet spinning process where the fiber enters the coagulation bath ...
