Calibration

Kinetic investigation and the Arrhenius plot The degradation of SAC in acidic, basic and oxidative mediums at different HCl (0.01, 0.05 and 0.1 M, keeping temperature 90 ºC), NaOH (0.005, 0.01 and 0.05 M, keeping temperature 40 ºC) and H2O2 (5%, 10% and 15%, keeping temperature 90 ºC) strengths was studied. Also SAC degradation was studied as a function of temperature in acidic (30, 60, 70, 90ºC and room temperature, keeping HCl strength 0.1M), basic (40, 65, 90ºC and room temperature, keeping…

The researchers compared both biologically produced manganese oxides and chemically produced manganese oxides for the oxidation of diclofenac. Because biologically produced manganese oxides are known to have high specific surface areas and high catalytic reactivity, this substance offers higher rates of oxidation for diclofenac when compared to chemically produced manganese oxides.² If biologically produced manganese oxides prove to completely eliminate diclofenac from the water supply, the…

While azulene and naphthalene have the same formula of C10H8, their differing arrangement of carbon atoms in rings causes disparities in their molecular orbitals. As shown in the energy difference calculations below Table 1, naphthalene has an energy difference of -10.184 between its HOMO and LUMO orbitals while azulene has one of +6.904. The low energy difference of naphthalene FMOs would suggest that its HOMO and LUMO orbitals have relatively similar distributions of electron density among odd…

2.1 Ageratum conyzoides Ageratum is derived from Greek word, which is “a geras” meaning non-aging, referring to the longevity of the flowers or the whole plant. The word “conyzoides” is derived from word “konyz” meaning resembles (M.X et al., 2016). Ageratum conyzoides is belongs to the Asteraceae family. Plant species in this family are herbaceous plants which trees and shrubs are rare. This plant is very common in West Africa and Asia. It has softly hairy stems and leaves, erect and branched…

but in case of low speed we should always choose high elastic moduli probe. Adhesion force measurement: Adhesion force measurement can be done during recording of the force vs displacement curve. This measurement has to be done in force calibration way. In the below plot point A indicates that the distance between the tip and the sample is too high, hence there is no interaction between sample and probe. After that, probe approaching the sample surface and the distance between the…

over actions, it favors being empiric as the base for a decisive action. Here, the metaphor of “Fire bullets, then Cannonballs”, is used to communicate a truth: bullets are low cost, less distractive and carry lower risk while granting time and calibration before firing of the cannonball. Approaching Chapter 5, the “Productive Paranoia” represented the concept of creative action. Preparation for worst‐case scenarios will reduce the chances that a negative event or bad luck will stop those…

Question 1: pH can be described as a measure of acidity or basicity (Alkalinity) of a solution. It is exactly equal in amount to the negative log of the concentration of hydronium(H3O+) ions. Due to the negative log relationship, increased hydronium ions transform to lower pH. When we add it to water, an acid releases hydrogen ion. Hydrogen ions in water unite with the water molecules to form hydronium ions, thereby lowering the pH and increasing the acidity of water. Water exposed to air is…

3. RESULTS AND DISCUSSION 3.1. Method development and optimization The main criterion is to develop successful HPLC method for the determination of FVS and its degradation product. The developed method should be able to determine FVS and its degradation product in a single run. This method should be accurate, reproducible, robust, stability indicating, free of interference from degradation products and straight forward enough for routine use in quality control laboratory. Regulatory agencies…

RESPONSE(LOD&LOQ): Replicate analysis of solution containing 300-900µg/ml and 30-90µg/ml of losartan potassium and amlodipine sample solutions respectively were injected into HPLC according to the procedure in a sequence and chromatograms were recorded. Calibration curves were constructed by plotting by taking concentrations on X-axis and ratio of peak areas of standards on Y-axis (Figs.3.A&B) and regression equation were computed for both drugs and represented in Table.2. The LOD and LOQ of…
