Biosorption of lead by marine green algae ulva lactuca from Industrial Waste Water

ABSTRACT The major changeling problem in recent times is dealing with environmental pollution. The water pollution is one of the main reason for health hazards caused due to high percentage of toxic heavy metals like lead, nickel, chromium etc. The non biodegradable nature of Lead is the prime reason for its prolonged persistence in the environment. Removal of lead deals with reason of maintaining healthy environment. The removal percentage of lead is performed by biosorption process using ulva lactuata and parameters are evaluated like pH, initial concentration, dosage, agitation time, temperature. The Lead removal percentage 90.76% is observed at various optimum parameters like contact time 83.06 min , dosage at 1gm, initial concentration 40 ppm , pH 4, temperature 313 K . From the optimized results, it is herewith to conclude that marine green algae ulva lactuca as a biosorbent in removal of lead is considered to be a promising and cheap mean to utilize for heavy metal removal from various industrial wastewater.
