In mangrove sediment I want to differentiate organic and inorganic sediment. I am having elements percentage available in the sediments (except carbon and nitrogen).

If you want to measure the weight of the organic part, you can weigh the sample before and after the use of hydrogen peroxyde which will remove it. There are standard protocols to do that.

The organic carbon content is the basis for differentiating organic and inorganic sediments. Without an estimate for organic carbon content, this is ntot possible. Instead, if you want to differentiate detrital and non-detrital sediments, then elemental ratios such as metal/Al or metal/Ti shall be helpful.

- You can determine the organic carbon in a laboratory geochemical analysis using the organic ignition method, it starts with the weight of the sample of sediments for example, between 0.5 g to 1 g in a small crucible that has been weighed before, then it put in a Muffle furnace in a degree 500 to 850 Co then it weight again after the ignition to solve the final equation of Organic Matter content: LOI % = (Wdry– Wign) x 100 / Wdry.
