3.7.1. Effect of solvent and pH The influence of the solvent on Schiff base ligand L and its metal(II) complexes were studied. The results showed that the optimal solvent for Schiff base ligand L, Co(II), Ni(II) and Cu(II) complexes were CH3CN at λemi =320, 310, 316 and 330 nm, while the optimal solvent for Mn(II) complex was DMF λemi = 312 nm, as shown in Figure 7. The effect pH on the fluorescence intensity of Schiff base ligand L and its metal(II) complexes were investigated between…

Meta description: Potassium phosphate is a supplement that is used to treat or prevent hypophosphatemia. Potassium phosphate is an injection supplement used as a preventative in order to remedy low phosphorus in the blood. Overview Potassium phosphate is an intravenous injection used to prevent or treat hypophosphatemia, low phosphorus in the blood, through the use of a concentrated solution mixture of monobasic and dibasic potassium. Phosphorus occurs naturally in every cell in the body and…

Section Two - Oral Liquid Formulations (1) Characteristics of Suspensions: The oral liquid dosage form chosen to formulate was that of a suspension. Given the criteria of Drug Y it was thought best to formulate the drug as a suspension. Suspensions can be defined as ''a class of materials in which one phase, a solid, is dispersed in a second phase, generally a liquid.'' (1) There are many characteristics of suspensions that are relevant when formulating such a dosage form. They are as follows;…

concentration the unknown was determined. Although there was no hypothesis made before the experiment as it was not required. With the required equipment, Hydrochloric acid was poured into a burette upto 0mL. A pipette was used to gather 25.0 cm3 of Sodium Hydroxide and transfer it into a Beaker. However during the experiment, 25.0 cm3 was converted into dm3, which resulted as 0.0250 dm3. The Beaker was placed underneath the Burette during the titration process. During the setup, a temperature…

1.4. Trihalomethanes 2. Ezbet El Moraba and Al Manshyia well water treatment plants 2.1. Physicochemical parameters Comparison between different physico chemical parameters was illustrated in table (6) and figures (15,16,17). The mean value of residual chlorine in Ezbet El Moraba well water treatment plant was 0.03 mg/L, while that of Al Manshyia well water treatment plant was 0.14 mg/L. The mean values of turbidity of Ezbet El Moraba and Al Manshyia well water treatment plants were 1.4 NTU and…

2.4 IL-DLLME procedures For IL-DLLME under optimum conditions, 10 mL of the sample solution containing Cd2+ or Ni2+ and PAN (10−5mol L−1) was adjusted to pH in a glass test tube with a conical bottom test tube. Using a microsyringe, the mixture of the extraction solvent ([Hmim][PF6]) and disperser solvent (acetonitrile) was rapidly injected into the previously mentioned aqueous sample. A cloudy solution (water, acetonitrile and [Hmim][PF6] ) was formed in the test tube. The ions reacted with…

Abstract For this experiment the amount of zinc in vitamin water had to be determined. To do this, three methods were applied. The first was by a calibration plot method, where zinc standards were prepared and from the absorbance of those standards a calibration curve was plotted, which in turn was used to determine the amount of zinc in vitamin water. The second method was standard addition. For this method, an un-spiked and spiked solution were prepared. The un-spiked solution only contained…
