以云杉不同光照强度的树冠枝条针叶和老针叶为试样，研究灰分中矿质元素的种类与分布特点和对亚甲基蓝的吸附，结果表明，阳面针叶中的矿质元素含量高于阴面，且K和Ca元素的含量高于Mg和Fe元素；老叶的矿质元素含量高于新叶，同样K和Ca元素的含量高于Mg和Fe元素。灰分在紫外可见光波长为650nm处时，亚甲基蓝的吸光度值最大；吸附平衡时间为70 min；0．4 g灰分为最佳用量；90℃时达到吸附平衡；在酸性范围内，随pH值增大，吸附力下降，碱性条件下则相反。

Picea asperata Mast.needles from crown branches and older needle -leaves with different light intensity were taken as objects to research the types and distribution characteristics of mineral element , and the adsorption to methylene blue.The results showed that mineral element content of sunny facing needles were higher than shaded halves , content of K and Ca were higher than Mg and Fe; Mineral element content of old leaves was higher than young leaves .Absorbancy of methylene blue reached maximum value , when wave length of ultraviolet visible light was 650 nm; adsorption equilibtium time was 70 min;0.4 g was optimum volume of the ash; adsorption equilibrium reached at 90℃.In the range of acidity, the adsorption capacity decreased with the increase of pH , the results was opposite in the range of alkalinity .
