hence, in future we can get concentration via A/0.0813 . (september 9 )
glass transition: point where stops being malleable (from high low T). between glass transition and melting it's malleable. 10 % clay was crosslinked very well so no melting (straight line i.e. no dip) . bottom line: water leaving. heat of melting crosslinked/ heat not crosslinked = percentage not cross-linked
max. absorbance for each run . in general to derive concentration . get mass of MG in mg that was not absorbed by beads. significant increase , almost exponential. total mg MG added after 35 ml : 1.75 mg capacity of beads: mass MG absorbed / g beads capacity measured vs gram dry beads. per dry mass gives you effective mass. per clay tells you how efficient clay is. capacity of dry beads: multiply by 5.56 (5.56 g wet beads / 1 g dry beads) calculate beads and clay capacity based on mass percentage and total absorbance of MG
concentration increased for Al (only if clay went through) Cu: increases quickly. plateaus around 60 ml after 12th sample. according to calculation, we expected absorbance to decrease after around 30 ml. total amount added Cu - amount coming out = 0.0566 mg absorbed. 1/3 was absorbed by beads. Zn: plateaus at 12 Pb: plateaus at 11 Na: starts high and gets low. significant decrease after first 5 ml. again at 7. minimum at 14 . Ca: less than Na. our clay has more Ca.
