Powder Pillows in Determination of Contaminants - Essay Example

Methods utilizing powder pillows are no exemption in these diverse fields of qualitative and quantitative analysis.

The procedures for the determination are as per method 8171, 8507, 8048, and 8155 respectively. A sample holder was filled with 25ml of the sample. The UV/VIS was tuned to the wavelength for the detection of the respective contaminant to be determined. A blank was run and used to zero the UV/vis spectrophotometer. Another sample holder was also filled with the sample to be studied and run at a similar wavelength as the blank. The reading of concentration in mg/L was taken and recorded for each of the samples.

When we compare, the concentrations of the four contaminants, the concentration of phosphorous reactive is very high compared to nitrate, nitrogen ammonia, and nitrite respectively. For the three samples, the values of these respective contaminants are the same signifying their source could be similar according to the water characteristics table 2. From the values, it can be deduced that the samples can be considered to be from grey water. Read More
