Standard Addition Connected to Selective Zone Discovering for Quantification in the Unknown Mixtures
Univariate calibration method is a simple, cheap and easy to use procedure in analytical chemistry. A univariate analysis will be successful if a selective signal can be found for the analyte(s). In this work, two simple ways were used to find the selective signals, spectral ratio plot (SRP) and loading plot (LP). Both of them were able to discover the selective regions in the recorded data set...
متن کاملDetermination of Protonation Constants of Some Tetracycline Antibiotics by Potentiometry and LC Methods in Water and Acetonitrile-Water Binary Mixtures
Uma estimativa acurada das constantes de dissociação de antibióticos tetraciclina em misturas binárias acetonitrila-água é muito importante para muitas técnicas de separação, como cromatografia líquida e eletroforese capilar que usam essas misturas de solvente. Neste estudo, os valores de pK a de cinco tetraciclinas (tetraciclina, oxitetraciclina, clorotetraciclina, doxiciclina e metaciclina) f...
متن کاملOrganic Matter and Water Addition Enhance Soil Respiration in an Arid Region
Climate change is generally predicted to increase net primary production, which could lead to additional C input to soil. In arid central Asia, precipitation has increased and is predicted to increase further. To assess the combined effects of these changes on soil CO2 efflux in arid land, a two factorial manipulation experiment in the shrubland of an arid region in northwest China was conducte...
متن کاملPredicting Adsorption of Water/Organic Mixtures Using Molecular Simulation
The use of Monte Carlo simulation to predict the adsorption of mixtures of polar and nonpolar species on acti®ated carbon was in®estigated using water and ethane on BPL carbon as a prototype system. The structure of the adsorbent was modeled by an array of slit-shaped pores, characterized by a pore-size distribution. The chemical heterogeneity of the carbon was taken into account by including o...
متن کاملAn Improved GEF Fast Addition Algorithm
In this paper, an improved GEF fast addition algorithm is proposed. The proposed algorithm reduces time and memory space. In this algorithm, carry is calculated on the basis of arrival timing of the operand’s bits without overhead of sorting. Intermediate terms are generated from the most significant bit and the carry is generated from the least significant bit using the functions of efficient ...
