What is Orthotolidine test?
orthotolidine test (o-tolidine test ; tolidine test) A presumptive test for blood that is also referred to by the shorthand notation of o-tolidine. This test works similarly to most other tests for blood in that the o-tolidine reacts with haemoglobin in blood in the presence of hydrogen peroxide (H… …

How do you perform an Orthotolidine test?
The first option for testing uses a liquid chemical OTO (orthotolidine) that causes a color change to yellow in the presence of total chlorine. You simply fill a tube with water, add 1-5 drops of the solution, and look for the color change.
What is Orthotolidine test of water?
Enables Total, free and combined chlorine in water to be determined with speed and accuracy. The reagent is ‘analytical grade Orthotolidine’, dissolved in 10% solution of HCl. When this reagent is added to the water containing chlorine , it turns yellow.
What is the importance of water purification?
Water purification can not only help remove harmful containment but also improve the taste, smell and visual appearance of your drinking water. It reduces the amount of chlorine, soil residue, and organic and inorganic substances.
What can you test for with orthotolidine solution?
Orthotolidine Solution. Testing of fluids such as urine and blood is a part of routine diagnostic forensic testing. As well, such testing can yield useful forensic evidence of disease, presence of toxins and other chemicals, and even genetic material.
What was orthotolidine used for in the past?
Orthotolidine Solution. In the past, orthotolidine was a popular chemical used to monitor swimming pool water for the presence of excess chlorine. While that use has been supplanted by other chlorine monitoring methods, orthotolidine has remained popular in routine diagnostic testing and in forensic investigations.
Can you take toluidine and orthotolidine together?
Orthotolidine can be combined with another chemical, toluidine, to assess the presence of myoglobin in urine. Presence of the latter is characteristic of a malady called myoglobinuria.
What happens when hydrogen peroxide reacts with orthotolidine?
Subsequently, peroxidase converts the hydrogen peroxide into a compound that reacts with orthotolidine. The result is a blue color. The blue reacts with the yellow dye in the strip to form a potential spectrum of color ranging from light green to a dark blue color.
