| Abstract: | The adsorption behaviors about methyl violet with tea-leaf powder were studied.After adsorption,the concentration of methyl violet in filtrate was determined by ultraviolet and visible spectrophotometry,the adsorption rate was calculated.The influenceable factors,including pH value,concentration of adsorbate,absorption time and amount of adsorbent were studied.The adsorptive ratio of methyl violet was 98% under such experimental conditions as：（a） the concentration of methyl violet was 20mg/L,（b） the volume of solution was 50mL,（c） pH value was 10.0,（d） the dosage of tea-leaf dust was 250mg and（e） the reaction time was 20min.The adsorption capacities of methyl violet on tea-leaf powder was 180.6mg/g. |
