Abstract

Throughout the past 50 years, water contamination has negatively affected the environment and its organisms. Heavy metals, such as lead, are one of the most common contaminants of water. Research was conducted to find a potential solution to treating lead contaminated water using zeolites: an aluminosilicate, crystalline structure. The purpose of this experiment was to determine if using larger amounts of zeolites would treat and purify the lead contaminated water more effectively than in smaller amounts. It was hypothesized that as the amount of zeolite increases, the percent transmittance would increase for the post-treated solution. Treatment was carried out by pouring a lead contaminated solution, composed of distilled water and lead (II) oxide, through different masses of zeolites which was then tested afterwards to measure the treatment’s effectiveness. A one-way ANOVA at ⍺ = 0.05 found that control group (n = 30, M = 63.29% SD = 12.63%), the 1.00 g (n = 30, M = 84.36%, SD = 9.53%), the 1.75 g (n = 30, M = 88.00% , SD = 6.71%), and the 2.50 g (n = 30, M = 90.78%, SD = 12.66%) were statistically significantly different (F(3,116) = 41.10, p = <0.001). A post-hoc Tukey test indicated that the test values for the 1.00 g (n = 30, M = 84.36%, SD = 9.53%), the 1.75 g (n = 30, M = 88.00% , SD = 6.71%), and the 2.50 g (n = 30, M = 90.78%, SD = 12.66%) all had statistically significant differences to the control group (n = 30, M = 63.29% SD = 12.63%), the 1.00 g (n = 30, M = 84.36%, SD = 9.53%). The hypothesis was not supported; as the data indicated that there were statically insignificant differences between the experimental groups excluding the control. However, the data does indicate that zeolites are an effective method in treating lead contaminated water.
