Polydimethylsiloxane composites containing 1,2-naphtoquinone 4-sulphonate as unique dispositive for estimation of casein in effluents from dairy industries
Abstract(#br)A unique dispositive to determine casein which is the most abundant protein in dairy sewages has been proposed. In this sensing technology, the derivatization reagent 1,2-naphtoquininone 4-sulphonate (NQS) is embedded into a polydimethylsiloxane-tetraethylortosilicate-SiO 2 nanoparticles composite (PDMS-TEOS-SiO 2 NPs). When the composite is immersed into the samples, casein is extracted from the solution and derivatized inside the PDMS matrix after 10\u003cce:hsp sp=\"0.25\"/\u003emin at 100\u003cce:hsp sp=\"0.25\"/\u003e°C.
