Poisoning
results from many reasons such as misuse or overdose of drugs. Suicidal and
murder purposes are mostly severe, serious and life-threatening cases which
require immediate intervention and treatment. Among lifesaving methods external
and/or internal decontamination is the most important. Internal decontamination
(gastrointestinal) is an effective process for intoxication control that can be
done by adsorptive materials. Activated charcoal is used as unique local
antidote for adsorption of causative agent. Considering their significance and
effectiveness, adsorptive materials are necessary to be developed. In the
present study, starch and naturally extracted pectin from citrus, in the
presence of trace amount of potassium per sulphate as initiator, were thermally
grafted to chitosan to form natural, inert, and highly adsorptive polymeric
surfaces. This polymer is convenient for 
 biomedical purposes. Upon drying
at 37°C for 48 hours, thermally cross-linked products were obtained. FTIR,
UV-Visible spectrophotometer and SEM analyses were applied in order to
characterize the products. To evaluate the adsorption potency of new adsorptive
material, lead and iron which cause common poisoning were applied on the
polymers. The results showed that adsorption degree of lead and iron were
maximum 50% and 30% respectively. Desorption amounts can be a sign of
adsorption potency. In this study, paracetamol and imipramine, which are
commonly used drugs that can and caused intoxication in case they are misused
or use for suicidal purpose were applied onto two polymers which contain pectin
desorption amount for two drugs were determined. SEM
pictures taken before and after blood/polymer contact didn’t reveal any
significant blood component attachment on the chitosan-graft- (starch; pectin) film surface. Indicating no
hemocompatibility.
