Influencing factors on bioaccumulation of Ni by Synechcoccus were studied in this paper. The equilibration time of Ni bioaccumulation was about 80 min in aqueous solution. Bioaccumulation quantity reached maximum when mass ratio of Ni to dry weight concentration of Synechcoccus was 16-18%. Bioaccumulation quantity increased with increasing pH. The optimum pH was 9-10 and higher pH led to precipitation of Ni（OH）2. Bioaccumulation quantity was also influenced by temperature and light intensity reaching their optima at 35℃ and 3 000 lx respectively. Bioaccumulation of nonliving algae was larger than that of living algae.
