moh le layan gambo2 ini..

act nie ada lah exp ke - 4 q utk sem ini/ thun ini..
exp nie sgt simple..
tjuknye adalah "Properties of Solid and Its Adsorption of Copper Ions from Aqueous Solution"

1. masukkn kire2 5mL of 1g/L copper solution dlm conical flask..then, fullfill the conical flask 50mL with distilled water..then, shake it to homogeneous the solution..
2. repeat step 1 for another volume which are 7.5mL, 10mL and 12mL..
3. then after finish the step, we weight around 1 g of adsorbent and mix it wif the each of the solution that we prepare b4..our group get decanter cake for the adsorbent..
3. we place the flasks on the orbital shake..we have to take sample for each concentration after 0, 20, 40 n 60 minutes and place it on micro centrifuge tube...after finish 60 minutes..we move the sample of each concentration to centrifuge in 5 minutes in order to form the precipitate n to avoid us from take that precipitate..
4. take 1 mL of the solution for each solution and dilute with 9 mL distilled water..then add a drop of HNO3..
5. analyse with AAS instrument..
