Abstract
Methods of physical and chemical adsorption of heavy metals, has some disadvantages such as high cost and are ineffective at low concentrations. Methods for biological uptake of heavy metals in recent decades were considered. Among the biological adsorbent include: bacteria, fungi and alga, algae have the highest efficiency of metal uptake. This study determined that the main role in the uptake of metals, nickel (II) and cadmium (II) Alginic acid is responsible. Focus serratus brown alga, as adsorbent in this study used a cost-effective biological and biological uptake of cadmium and nickel ions simultaneously in a batch reactor has been studied. Surface structure of algae has been studied. Adsorption kinetics have been studied, the equilibrium time is about 300 minutes, the Langmuir adsorption isotherm using the equation can be interpreted as the maximum adsorption of about 0/85and 0/95mmol/g are, respectively, for cadmium(II) and nickel(II).

Abstract
Cadmium is an important environmental pollutant with much application. The main use of this metal is in electroplating and used as a cathode material for nickel cadmium batteries. Chronic exposure to cadmium can result in damaging of various tissues such as the liver, kidney and tested. In this study, we used cadmium chloride at a dose of 2mg/kg, taurine at a dose of 400mg/kg both were used intreperitneal administration for the long-term treatment for 4 weeks (two days in week). The parameters include relative testicular weight, body weight, testicular volume, the thickness of tunca alboginea and spermatogonia A and B, spermatocyte, spermatid, leyding cell and sertoli cellwere investigated. The results indicated that cadmium significantly increased the thickness of tunca alboginea and relative testicular weight, whereas, the other parameters were significantly decreased also no change never observed after treatment with a combination of taurine and cadmium. This results demonstrated that cadmium induced damage was protected by taurne in mice.
