Hcl Medium

In HCl medium and in the presence of CuSO4, Na3AsO4 can be reduced by NaH2PO2 to form As nanoparticles (AsNs) which exhibited a strong resonance Rayleigh scattering (RRS) peak at 370 nm. Under the chosen conditions, the increased intensity at 370 nm was linear to As5+ concentration in the range of 0.48-38.0×10-6 mol/L, with a regression equation of ΔI370nm = 82.3 CAs + 33.9, a correlation coefficient of 0.9878 and a detection limit of 2.0×10-7 mol/L As5+. The proposed method was applied to detect As5+ concentration in waste water, with simplicity, rapidity and accuracy. Thus, a novel RRS spectral method was established to determine As5+.

The article describes solution of the task of developing a wide-range device for measuring the chlorophyll а concentration in seawater. The principle of operation is based on remote determination of ranges where the pollution degree exceeds a certain threshold value where the change of regimes is required. The author has noted that the threshold value can be based on both sanitary norms and objectives of the system effective operation. The conducted research resulted in development of the general concept of the wide-range ground/board-based system for determining the degree of seawater pollution with chlorophyll. The author has developed an operational algorithm of the above system functioning and has analyzed the issues of the optimal structuring of the system.
