Technical solutions for determination of membrane permeability of emerging contaminants in liquid phase using 3D printing
Original language description
Pollution of water with emerging contaminants is a worldwide problem. To determine the permeability of membranes to the contaminants in the liquid phase, a device with surface plasmon resonance (SPR) detection was designed. The device consists of two cells located on the SPR sensor; the upper chamber is flow-through that ensures a constant concentration of analyte above the membrane, while the lower chamber below the membrane is stationary and the SPR sensor is located at the bottom. As a reference method, steel Franz diffusion cells have been constructed, as well as plastic cells printed by 3D printing. The cells are then tested for both artificial membranes (e.g. polyethersulfone) and natural membranes (plant cuticles) with selected analytes from the group of pesticides (e.g. metazachlor) or pharmaceuticals (e.g. paracetamol). In the case of 3D printing, the dimensions of the cell defining the acceptor volume and active area of the membrane can be easily adapted. It is also possible to attach capillaries to the donor chamber and determine the permeability of substances in a cross-flow arrangement. In the case of the SPR method, online detection allows continuous and fast determination of membrane permeability for the selected analyte.
