What does the negative sign mean in Langmuir's isotherm?
This is langmuir' equationQe = QmbCe / (1+bCe) where as Qe= heavy metal adsorbed to adsorbent (mg/g)Qm = maximum adsorption capacity (mg/g)b= langmuir 's constantCe =equilibrium concentration of heavy metal solution (mg/)when i set it as LINEAR 1/Qe = 1/Qm + (1/bQm)(1/Ce)when i plot 1/Qe againt with 1/Ce i got y = 81.6X -6.8and i am wondering1.what does it mean with this negative sign (-6.8) when calculate the intercept Y = 1/Qm2. i need to calculatedintercept Y = 1/Qm = 1/-6.8 so Qm = -0.14?? or only 1/6.8Thank you for you help :))
