Having been exposed into the ocean, heavy metals were accumulated within organism. In the food chain, the higher rank of predator takes the more amount of heavy metals into its own body. Once accumulated, heavy metals were hardly decomposed or excreted. So heavy metals in the ocean could take place heavy metal poisoning and ecocide. As a result, this study were purposed to develop ocean heavy metal bio-sorption process using micro algae. Through the screening, some micro algae having an ability to remove heavy metals, Chlamydomonas reinhardtii, Chlorella sorokiniana, Chlorococcum littorale and Ettlia oleoabundans were selected. Then bio-sorption ability of the heavy metal containing As, Cd, Co, Cr and Zn was measured by ICP-OES. These four kinds of micro algae were immobilized in the beads to perform the continuous heavy metal sorption process.
