运用回归分析原理，讨论了浓度、时间及不同物种对生物聚金富集率的影响，并和粘土矿物吸附金作了对比。结果显示：生物对金的富集导致富集率的急剧上升是在较短的时间内完成的，其动力机制在于生物对金的被动吸附及细胞壁对金的络合作用；时间与金溶液浓度同为影响生物富金的重要因素，金溶液浓度的影响远较时间因素显著；生物富金与无机物吸附金相比，无机物吸附金是一个较为缓慢的过程，时间作为影响吸附能力的一个因素，其显著性大大提高。
Using the principle of regression analysis, the effects of concentration, time and different species on the enrichment rate of bio-poly-gold were discussed and compared with that of clay minerals. The results showed that the bio-gold enrichment led to the rapid increase of enrichment rate in a short period of time, and its dynamic mechanism lies in the biological adsorption of gold and the complexation of cell wall with gold. The time and gold concentration As an important factor affecting the bio-rich gold, the concentration of gold solution is far more than the time factor; compared with inorganic gold adsorption, inorganic gold adsorption is a relatively slow process, as a time affecting adsorption capacity Factors, their significance is greatly improved.
