本實驗中，將花生殼置於方形高溫爐中，在500℃煅燒30分鐘，製成花生殼灰。利用感應耦合電漿質原子發射光譜儀、掃描式電子顯微鏡、表面積測定儀、密度測定儀、粒徑分佈儀、水份天平及pH計對花生殼灰進行組成分析及物理性質之觀察或測定。
接著，以花生殼灰當吸附劑，對含鉛離子水溶液進行吸附，實驗結果發現，以去除速率及平衡去除量來看，花生殼灰都是良好的吸附劑。另外，我們發現，降低花生殼灰劑量或提高鉛起始濃度有利於鉛離子的去除。在高花生殼灰劑量, 3.0 g/L下，pH值、震盪速率及吸附溫度不會影響吸附量。但是在低花生殼灰劑量， 0.2 g/L時，提高pH值或吸附溫度則會提升吸附量。
另外，Langmuir吸附等溫式比Freundlich吸附等溫式更適合描述Pb2+/PHA的吸附。利用平衡吸附的數據算出了下面的熱力學參數: Kc、G、H、和S。
擬二階速率式可合適的迴歸本實驗中的動力學數據，最後迴歸出一條鉛離子去除量和吸附時間的關係式。

In this experiment, peanut hull was ashed at 500℃ for 30 minutes. The content and the physical properties of peanut hull ash (PHA) was analyzed using an inductively coupled plasma atomic emission spectrometry, a scanning electron microscope (SEM), a surface area analyzer, a density meter, amoisture determination balance and a pH meter.
PHA thus produced was found to be effective in removing lead(II) ion from aqueous solution. Experimental results indicated both the rate of removal and the removal at equilibrium were increase with decrease PHA dosage or increase initial lead concentration. pH, stroke speed and adsorption temperature, however were found to have no effect on the rate of removal and removal at equilibrium for the high PHA dosage, 3.0 g/L . High value of pH or adsorption temperature, however, might increase the removal for the low PHA dosage, 0.2 g/L. The data obtained at equilibrium were better represented by the Langmuir isotherm than the Freundlich one. Thermodynamic parameters for the adsorption process. That is Kc, G, H and S have also been calculated.
The overall process was found to be suitably interpreted by pseudo-second-order rate equation. An empirical relationship between the removal of Pb2+ and adsorption time was also determined.
