تم تحضير ثلاثة مركبات عضوية فوسفورية تحتوي الجسر =P(S)-NH-P(S)= مع متبادلات الفينيل (PhO) , (Ph) متماثلة و غير متماثلة لاستخدامها كمواد مستخلصة لعنصر البلاديوم وفقاً لطريقة الاستخلاص ( السائل – السائل ) ذات الأهمية الكبرى في استخلاص المعادن النبيلة و عناصر الأتربة النادرة، و حُددت بعض خواصها الفيزيائية و الكيميائية ( درجة الانصهار , طيوف UV , طيوف IR ) . اعتُمدت الطريقة الفوتومترية لتحديد تراكيز أيونات معدن البلاديوم في الوسط المائي استُخدم محلول 2- نتروزو,1- نفتول لتحديد التراكيز وحُسبت قيم تراكيزه في الطور العضوي اعتماداً على الفرق بين التراكيز البدائية المحضرة له في الوسط المائي و التراكيز النهائية بعد عملية الاستخلاص . دُرس عامل توزع أيون البلاديوم DPd بين وسط مائي من محلول حمض كلور الماء و وسط عضوي يحتوي تراكيزاً مختلفة من المركبات الفوسفورية العضوية المحضرة سابقاً ، كما دُرس توزع أيون البلاديوم بدلالة تغير قيم الـpH عند تركيزٍ ثابتٍ من المستخلص المستخدم المذكور سابقاً و قُيمت معلومات التوزع رقمياً و بيانياً .
Three organic phosphorous compounds containing bridge = P(S)-NH-P(S) = with , (PhO) , (Ph) acting noble metals and rare earth elements, and identified some of the chemical and physical properties (melting point, spectra UV , IR ) . Photometric method adopted to determine the concentrations, as it used the solution of 2-Nitroso, 1- Naphthol to determine the concentrations of palladium ion in the aqueous phase after extraction and its concentrations in the organic phase based on the difference between the concentrations of primitive prepared and the final concentrations. Distribution Ratio DPd was studied of the ion palladium between the aqueous medium of the acid solution of hydrochloric and central Organic Dilutions containing different concentrations of the previous prepared organo phosphorus compounds also was studied the Distribution Ratio DPd of ion palladium depending of changing of pH-values in aqueous medium and central organic Includes fixed concentration from the previous prepared organo phosphorus compounds and evaluated the distribution of information focus numerically and graphically .

The study addresses the synthesis of two organic phosphoric compounds that have
the P-NH-c bridge, They have the following chemical formula (PhO)2P(O)-NH-C(CH3)=CHCN
( abbreviated as PCNO) and The compound (abbreviated as PCNS) The compound
were s
ynthesized in the center of acetonitrile and having a strong base of sodium hydride
NaH by Diphenyl chloro phosphate (PhO)2POCl compounds and Diphenyl chloro thio
phosphate (PhO)2PSCl compound Respectively . Some of the physical and chemical
properties of the synthetic composites, such as the melting point, dissolution , and the
withdrawal of some important spectra such as the IR spectra and the NMR spectra were
used in the extraction of the copper(II) Ions from the of medium sulphates, Lesson of
Partition Coefficient Copper Dcu between aqueous medium of organic medium containing
different concentrations of organic phosphorus compounds prepared previously. Partition
Coefficient copper(II) ion distribution was studied in terms of the change in the value of
PH (PH = 4 --- 6) at the constant concentration of the extract used previously .The
Spectrophotometer for calculating copper concentrations was used Depending on absorption ,
and the two previous components were compared .
A new colorimetric analytical method was developed for determination of
Lisinopril in bulk and tablets .
The method is depended on derivatization chemical reaction between
Lisinopril and 4- nitrobenzene diazonium tetra fluoro borate in non
aqueou
s medium to give color derivatives with max. absorption at 293.8 nm
.
The resulting color was measured spectrophotometrically . The absorbance
concentration plots were recti linear over the range 5-50 μg /ml.
The method applied for determination the Lisinopril in Tablet, The
percentage recoveries was 98% ± 2.4.
The results obtained were in accordance with those found using the HPLC
standard method in Pharmacopoeia .
In this research we have synthesized a new macrocyclic Schiff base (II)
containing nitrogen- oxygen donor atoms which was designed and synthesized
by reaction of: 1,4– bis (6',6'- methoxy -3- formyl phenyl)-1,4- dioxa butane (I).
Identification of
this macrocyclic schiff base: (II) 1,16- Diaza–[3,6;11,14-di
(6',6'- methoxy phenyl)]-7,10,19,22 - tetraoxa cyclo tetra icozane-15,1dien was
determined by (LC-MS) and spectroscopy (IR). The liquid- liquid extraction of
metal such as Zn2+, Pb2+ and Ni2+ from aqueous phase to organic phase which
doesn't in water. The effect of chloroform and dichloromethane as organic
solvents over the metal extractions was investigated at 25± 0.10C by using
atomic absorption Spectrometer and extraction percentage was calculated.
In this article, a polyester amide was synthesized from oleic acid. This polymer is a biodegradable and thermoplastic polymer, with wide medical and biological applications due to its being compounds with a linear structure. The polymer structure has
been confirmed. Output using spectroscopy methods known as 1H-NMR, and FT-IR spectroscopy. And we obtained this polymer with a good yield (78%).
Information extraction is the task of finding structured information
from unstructured or semi-structured text. It is an important task in
text mining and has been extensively studied in various research
communities including natural language proc
essing, information
retrieval and Web mining. It has a wide range of applications in
domains such as biomedical literature mining and business
intelligence. Two fundamental tasks of information extraction are
named entity recognition and relation extraction. The former refers to
finding names of entities such as people, organizations and
locations. The latter refers to finding the semantic relations between
entities.
