Preparation and composition of Sago waste as an adsorbent:
Sago
palm(Cycus revoluta) a green leafy ornamental plant http://en.wikipedia.org/wiki/Cycas_revoluta .It
is mostly cultivated due to its beautiful long green leaves .If it is
ingested by man it will be very dangerous some species of it are extremely
poisonous.It propagates mostly through seeds.
Sago waste as an adsorbent:
Firstly
twig off all the leaves and spread all the leaves onto the paper. Keep all
the leaves on sun exposure, to set dry. Later the dried leaves grinded to obtain powder of raw leaves. Further passed such dried powder
from the sieve in order to get more refine powder.in the long run introduced
the powder into oven at low temprature and let allow the powder moisture free. Now the adsorbent
is ready to use.Pack the adsorbent in an air tight container.
The composition of sago palm:
Trunk weight varies from 800 kg to 1250 kg and pith weight
varies from 643-850 kilograms. The pith contains 20.2 -29% starch and 50-66%
water, the remainder being 13.8-21.3 per cent. Calculated on the basis of dry
matter, the pith contains 54- 60% starch and 40-46% of other dry matter. The
bark or cortex varies from 25.7% -32% of the trunk.
Regarding sago, the granular starch size ranges from about
5-80 micro meters with an average of 30 microns. About 90% of the starch has a
particle size of between 20-40 microns. Sago starch consists of 27% amylose and
73% amylopectin. Its gelatinization temperature is 700 centigrade.
