KINETIC STUDY OF LIQUID-PHASE ADSORPTIVE REMOVAL OF HEAVY METAL IONS BY ALMOND TREE (TERMINALIA CATAPPA L.) LEAVES WASTE ABSTRACT. The kinetic sorption of five metal ions - Al3+‚ Cr6*‚ Zn2+‚ Ag+ and Mn2+ - from aqueous solution onto almond tree leaves (ATL) waste in single component system has been studied. The experimental data was analyzed in terms of intraparticle diffusion and rate of adsorption‚ thus comparing transport mechanism and chemical sorption processes. The sorption rates based on

without metal. The metals we use in our houses are mostly for keeping them sturdy. Though there is one problem we have when it comes to metals. That problem is that they rust. Metals rust when they are in contact with oxygen‚ and water. They rust much faster when they are in contact with salt water‚ and acid rain. We chose to see what would happen to various metals when they contacted with salt water. When the electrons move around in the salt water‚ it causes the metals to rust. The metals we chose

Ryan Stephens EN1320 04/13/2015 Rhetorical Analysis of “I have a dream speech” The main point of Dr. Kings speech was that an injustice had been done to the black people. They were promised freedom from the emancipation proclamation‚ and up to that point they still were not free. They were segregated and treated like second class citizens. Were they supposed to just sit down and let white men at that time humiliate them‚ beat them‚ bomb their houses‚ and strip them of human dignity

Background: Cumberland Metal Industries (CMI) was one of the largest manufacturers of curled metal products in the country.Their sales grew from $250‚000 in 1963 to over 18‚500‚000 by 1979.It originally custom fabricated components for chemical process filtration and other highly technical applications. The company’s philosophy soon evolved from selling the metal as a finished product to selling products that used it as a raw material . Earlier CMI used to sell exaust gas recirculation(EGR) valves

Lab 3: Mitosis and Meiosis Purpose: The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Hypothesis: I predict that

Laboratory 3: Molarity Of Saline Solution Data: Please write your observations about the appearance of the solution. 1. Normal Saline- The solution appeared clear at the start with slight particles showing‚ once adding the salt it still appeared clear. 2. Nasal Irrigation Saline- Solution appeared cloudy once adding the salt and baking soda‚ then it turned semi-clear about 30 secs later; it was more concentrated than the normal saline. Results: 1. Determine the molar mass of NaCl. Show the workup
