water environment

Information about test-methods discovering and quality determination pesticides, polycyclic aromatic hydrocarbons, hydrocarbons of oil, phenol and it’s derivative, halogen- and nitrogen-containing organic substances, surfactants in water environment. There are different methods indication analytical signal for appreciation of containing analyzing components and ranges and low levels determining containing. Different test ways are presented used for express test indicated mentioned organic substances in some object.

The unmodified and modified by polyaniline and nanoparticles planar potentiometric sensors on the basis of tetradecylammonium associates with a complex silver (I) – cefazolin are created. Optimum ratios of components in carbon-containing ink are established: 30–32% carbon powder, 16–18% polyvinylchloride, 48–50% dibutylphthalate and 1–3% of electrode active compound (EAC). Planar sensors of two types are examined: electrode active compounds, electrode active compound and modifiers were added into in carbon-сontaining ink.
