The observation is reasonable because increasing the initial concentration of lead increases the gradient of concentration or the driving force of a diffusion of Pb^+2 to the mass of the biosorbent. Hence, the percent removal of heavy metals depends on the initial metal ions concentration, thus; decreases with an increase in initial metal ions

2011-8-16 Lead (Pb), with atomic number 82, atomic weight 207.19, and a specific gravity of 11.34, is a bluish or silvery-grey metal with a melting point of 327.5°C and a boiling point at atmospheric pressure of 1740°C. It has four naturally occurring isotopes with atomic weights 208, 206, 207 and 204 (in decreasing order of abundance).

2001-11-7 Lead in the body comprises 2% in the blood (t 1/2 35 days) and 95% in bone and dentine (t 1/2 20–30 years). Blood lead may remain elevated for years after cessation from long exposure, due to redistribution from bone. Blood lead concentration is the most widely used marker for inorganic lead exposure.
