ABSTRACT:
A method of identifying different brands of peat moss including the steps of separation of the peat and sand by first adding water to the peat and sand mixture to enable the peat to float to the top of the water and the sand to gravitate to the bottom collecting the peat at the surface of the water and drying the peat there after grinding the peat to pass thru a sieve of small mesh then mixing the ground peat with Potassium Bromide (KBr) at a ratio in the neighborhood of 1:20 then grinding said mixture with a mortar and pestle then loading to a sample cell; then loading a ground pure KBr to a reference cell, then scanning and collecting wave spectrums of the references and samples in the range of 4000 to 600 cm−1, collect said spectrums directly from said peat/sand mixtures and dry said peat/sand mixtures in the neighborhood of 105 degrees centigrade for a 24 hour period.
