Densities, Viscosities, Heat Capacities, and Vapor–Liquid Equilibria of Ammonia + Sodium Thiocyanate Solutions at Several Temperatures
Journal of Chemical & Engineering Data, 2011Co-Authors: Shrirang K Chaudhari, Daniel Salavera, Alberto CoronasAbstract:Several thermophysical properties were experimentally measured for the ammonia + Sodium Thiocyanate mixtures at several temperatures: density from (269.4 to 350.9) K, dynamic viscosity from (269.8 to 369.5) K, and isobaric heat capacity from (304.17 to 364.15) K, all them at a constant pressure of 3 MPa, and vapor–liquid equilibria from (253.1 to 393.1) K. All properties were measured in a range of composition from 0.35 to 0.90 in ammonia mass fraction. The experimental techniques used were a vibrating-tube densimeter, a piston-style viscometer, a heat flux Calvet-type calorimeter, and a static method, respectively. The measured data were correlated as a function of temperature and composition using empirical equations and were compared with literature values.

second law based thermodynamic analysis of ammonia Sodium Thiocyanate absorption system
Renewable Energy, 2010Co-Authors: Linghui ZhuAbstract:In this study, the first and second law of thermodynamics are used to analyze the performance of a novel absorption system for cooling and heating applications. The active component of the sorbent used in this study is Sodium Thiocyanate (NaSCN). Ammonia (NH3) is chosen as sorptive. A mathematic model based on exergy analysis is introduced to analyze the system performance. Enthalpy, entropy, temperature, mass flow rate and exergy loss of each component and the total exergy loss of the system are evaluated. Furthermore, the coefficient of performance (COP) and exergetic efficiency of the absorption system for cooling and heating processes are calculated from the thermodynamic properties of the working fluids under different operating conditions. The results show that the COP of cooling and heating increases with the heat source temperature and decreases with the cooling water inlet temperature, but the system exergetic efficiency does not show the same trends for both cooling and heating applications. The simulation results can be used for the thermodynamic optimization of the current system.

rapid and simple detection of Sodium Thiocyanate in milk using surface enhanced raman spectroscopy based on silver aggregates
Journal of Raman Spectroscopy, 2014Co-Authors: Xiang Lin, Wuliji Hasi, Xiutao Lou, Shuang Lin, Fang Yang, Baoshen Jia, Yu Cui, Dianyang LinAbstract:Surface-enhanced Raman spectroscopy (SERS) was used for rapid detection of Sodium Thiocyanate in milk employing silver aggregates as active substrate. Silver nanoparticles were induced to silver aggregates by trichloroacetic acid (TCA). The limit of detection (LOD) for Sodium Thiocyanate was 10−2 µg ml−1 in water with an analytical enhancement factor of 5.4 × 106. The silver aggregates represent good reproducibility and stability. Good linear relationship was obtained for Sodium Thiocyanate in milk at concentration ranges from 0.1 to 10 µg ml−1 (R2 = 0.995). Using TCA as protein precipitator, silver colloid would aggregate spontaneously when mixing with samples during SERS measurement without the need of additional aggregating agent. The simple pretreatment procedures and analytical methods are less time consuming (<10 min) and environmentally friendly, making the proposed method much practical for in situ detection of Sodium Thiocyanate in market milk.
