CHARACTERISATION AND SORPTION PROPERTIES TO HEAVY METALS (Cu2+, Pb2+) OF CHITOSAN COMPLEXES EXTRACTED FROM COCKROACHES OF RWANDA

ABSTRACT
Cockroaches of Rwanda are one of the most important sources of chitosan. In chitosan extraction from Cockroaches, conditions for deproteinization were: 8% NaOH at 95 ºC for 1 h and demineralization involved treatment with 6.7 % HCl at room temperature. Yield of extract products was ..... Chitin-glucan insoluble complexes in the extracted products were identified by FTIR specus ....etc

Introduction.
 Composite materials are particularly attractive to aviation and aerospace applications because of their exceptional strength and stiffness-to-density ratios and superior physical properties.
 As the technology matured, the use of composite materials for primary structures such as wings and fuselages has increased. Initial applications of composite materials to aircraft structures were in secondary structures such as fairings, small doors and control surfaces ....etc

RELAXATION TIME ť
FOR TYPICAL MONO-VALENT METALS
IS SHOWN IN TABLE

The conductivity σ may be obtained experimentally .
Further we can get ť by using eqn given below
σ = ( n*Qe2 *ť )/me ---------(1)
but ť obtained may not be accurate but we will get an idea of magnitude of ť . In a monovalent metal no of free e- /m3 is equals the no of atoms /m3 . From table we find that relaxation time T is of the order of 10-14 sec .Thus we can ....etc

BIOSORPTION OF METALS


SELECTION OF BIOMASS
While choosing the biomass for metal biosorption, its origin is a major factor .

Biomass can come from, activated sludge or fermentation waste from industries like those of food, diary and starch .

organisms coming from their natural habitats are good sources of biomass.

Fast growing organisms that are specifically cultivated for biosorption purposes


TYPES OF BIOMASS

Agricultural products

Seaweed ....etc
