Waste water total inorganic carbon value determining method involves bringing dry substrate in contact with sample of water to be tested in total inorganic carbon reaction container

摘要

Waste water total inorganic carbon value determining method involves shifting porous substrate (7) with phosphoric acid of sufficient concentration. Liquid phase is filtered off for a predetermined residence time. The moistened substrate is dried for instance 150[deg]Celsius. The dry substrate which is stored under air supply is supplied to customers and users, and brought in contact with sample of water to be tested in a total inorganic carbon (TIC) reaction container (2). Independent claims are also included for the following: (1) a total inorganic carbon material for implementing the method for determining total inorganic carbon (TIC) value; (2) an arrangement for implementing the method for determining total inorganic carbon (TIC) value.
