ديه الحاجات اللى دكتورة ناهد قالتها فى اخر المحاضرة
give reason:
1-benzocaine in 0.1 mole hcl exhibit hypsochromic shift,
hypochromic effect
2-flourescent impuritieshave high transimeted light
as high impurities decrease absorbance
3-water, methanol best solvent of choice in spectrophotometery
4-phenol in 0.1naoh exhibitbatho,hypso
5-photomultiplier>photo cell
6-presence of capo4,AL2O3 are greatly interfere inAAS
explain:-
1-effect of pH on absortion spectrum of benzocaine,paracetamol,dichromate
2-how to remove interference from highly ionized comp byASS
3-source of excitation in flame specro scopy
4-source of excitation in flame AAs
how to analyse each of the following:-
1-atenolol , spirolactone , amantadine , pyridoxide,mix. of ca, mg in water, mixture of metobromide(مع حاجه مش عارفاها )
spectro photometry)
2-captoprile, oxiandine , tameflue , aspirin.
( fluorometry )
3- NACL , LICL2, CACL2 , LORATIDINE , TERFENADINE , PHENOTHIAZINE . (AAS)
4- Sulfa acetamide ( مش فاكره تبع ايه )
defination and exmple ( شفوى غالبا )
chromophore , auxochrome , acid dye mechanism , charge transfere mechanism , bathochromic , hypsochromic , inter system crossing prosses , vibration relaxation , resonance fluorescence , fluorescence , phosphorescence .
Diagrame With ( رسم بالبيانات فقط الا اذا طلب مميزات و عيوب ) 1-transition leading to fluorescence
2- transition leading to phosphorescence
3- total consumption burner
4- lamellar cobellar , advantage
5- mono cathode lamp)ممكن تكون hollow cathode lmp)
وطبعا الحاجات اللى قالت عليها مهمه فى المحاضرات طول السنه وقالت اى حاجة قولتها فى المحاضرات انتو مطالبين بيها
معلش ياجماعه هتلاقوا فى حاجات غلط فى spellingاصل دكتورة ناهد كانت بتتكلم بسرعه وده اللىلحقت اكتبه وراها فلو حدلقى حاجة ناقصه ياريت يكتبها وربنا يوفقنا كلنا ان شاء الله
ادعولى ربنا يرزقنى بالخير
