Abstract
Hevea braciliensis is a tree discharged white colored latex that is utilized to produce natural rubber. Generally, two types of rubber sheet such as Ribbed Smoked Sheet (RSS) and Air Dried Sheet (ADS) are produced in the world. Ribbed Smoked Sheet is the most popular than the Air Dried Sheet which is used for the production of huge end products like tyres, condoms, surgical gloves, balloons, adhesive, rubber band, carpet backing etc. It is produced by applying some steps named latex collection by tapping process, preservation, coagulation, sheet formation and smoke drying. Three samples of Ribbed Smoked Sheet were collected from the hilly area of Chattogram. Nine metals viz. Chromium (Cr), Cobalt (Co), Nickel (Ni), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Lead (Pb), Cadmium (Cd) have been measured in these samples. The experiment revealed that the concentration of Cr, Co and Ni for all samples was found in Below Detection Limit. Mn was obtained in the range of (3.11 – 4.24) ppm where Fe, Cu, Zn, Pb and Cd were measured in the range of (19.06 – 27.28) ppm, (1.98 – 4.40) ppm, (0.75 – 5.22) ppm, (BDL – 4.13) ppm and (BDL – 1.73) ppm respectively. Among these metals, Iron was found as the highest concentration (27.28 ppm) in a measured sample.
